Getting Started
What should I understand before commissioning a bespoke watch strap?
Bespoke watch straps are not commodities. They are functional design objects shaped around a specific watch, wrist, and way of wearing.
Unlike standard straps designed around averages, bespoke considers curvature, taper, thickness, clasp position, and real-world wear. These details determine whether a watch feels settled and effortless — or quietly distracting every time you wear it.
Who commissions INRO London?
INRO is for owners and collectors who care about how their watch actually wears.
Whether it’s your first meaningful watch, a long-sought grail, or a restored vintage piece, our clients value comfort, proportion, and considered design — not generic solutions.
Can you help with vintage watches or discontinued straps?
Yes — this is a core part of our work.
Vintage watches and discontinued strap references often require bespoke solutions, particularly where original deployants, fixed buckles, unusual lug geometry, or uncommon proportions are involved. Where required, we assess the watch, hardware, and wrist in person so the result feels correct and balanced — without relying on standard sizing.
Do you specialise in bespoke Cartier watch straps?
Yes — this is a core part of our work. We work extensively with Cartier, particularly vintage and classic models such as the Tank, Santos, and Tortue.
Many Cartier pieces require bespoke straps due to original deployant clasps, fixed buckles, and brand-specific proportions — particularly with discontinued references. The aim is a strap that wears as Cartier intended: settled, centred, and effortless.
Do you create bespoke straps for Patek Philippe watches?
Yes. We create bespoke straps for Patek Philippe watches, with particular attention to proportion, comfort, and compatibility with original deployant clasps.
We keep the finish understated and the proportions restrained, so the strap supports the watch rather than announcing itself.
Consultation
Why is consultation important when commissioning a bespoke strap?
Because fit and balance cannot be standardised.
During consultation we assess wrist profile, wearing preference, watch proportions, curvature, taper, thickness, hole placement, and clasp compatibility — especially important for vintage watches and original deployant clasps.
Consultations are held by appointment at our Marylebone studio.
Do I need an in-person consultation every time?
Not necessarily.
Your first commission usually benefits from an in-person consultation, as we can establish your core fit, wearing preferences, and the proportions that suit you best. Once your details are known, additional straps can often be commissioned more efficiently — with only a watch-specific review needed for each piece.
Where required (particularly for vintage watches and original deployant clasps), we may recommend an in-person fitting to ensure everything feels correct on the wrist.
Can we do this without a consultation if I’m not in London?
Yes — we regularly work with clients remotely and can get very close to an ideal fit with the right information.
At minimum, we need the lug width and buckle / clasp width.
To optimise the strap as accurately as possible from a distance, we typically ask for:
- Lug width (mm)
- Buckle / clasp width (mm)
- A quick photo of the watch laid flat
- If available, the reference/model number — the fastest way for us to cross-check everything at our end
From there, we advise on the most suitable strap shape, taper, and construction for your watch, clasp, and wearing preferences.
For ultimate precision, the final “perfect” feel is always achieved in person — as how the watch and clasp sit on the wrist can only be assessed in real wear. Once we’ve completed your first strap for that watch, we keep the details on file for future commissions.
If I already have a strap that fits well, can you replicate it without an in-person consultation?
Yes — and this is often the most accurate way to commission a strap remotely.
If you have an existing strap that fits and wears exactly as you like, we can work from its measurements to replicate the fit in your chosen leather and finish. This allows us to preserve the proportions you’re already comfortable with, while upgrading the material, construction, and overall refinement.
We can either match the exact measurements of your current strap, or adjust them if you’d like to refine the sizing or change how it wears.
You can either share a few key measurements, or send the strap to our atelier and we’ll take care of everything from there.
Once your first strap is completed for that watch, we keep your specifications on file — making future commissions seamless and precisely repeatable.
Do I need to know what material or colour I want?
No — we guide you.
Too much choice often creates uncertainty rather than clarity. Once we understand your watch, style, and how you wear it, we curate a focused set of options that are known to work — technically and aesthetically.
Our aim is clarity, not overwhelm. Every decision is guided, never assumed.
Can you match an original strap exactly?
In most cases, yes.
If you wish to retain the original look, we can replicate material, colour, stitch style, and overall proportions. This is especially common when replacing original straps for vintage watches and classic pieces such as Cartier.
Fit and comfort can then be refined discreetly, without altering the watch’s identity. Alternatively, we can subtly evolve the design — as long as it remains appropriate to the watch’s character.
Can you reuse my original clasp or deployant clasp?
In most cases, yes — and often advised.
Many clients prefer to retain original hardware for comfort and authenticity. Compatibility is confirmed and the strap is designed around it.
Can you build a strap specifically for an original Cartier deployant clasp?
Yes — and in many cases, this is exactly how the strap should be made.
Original Cartier deployant clasps are designed to work with specific strap proportions. During consultation, we assess the clasp geometry, condition, and how it sits relative to the case and wrist, then design the strap around the deployant clasp — never forcing a standard strap to fit.
What matters most when fitting a strap to a Patek Philippe?
Restraint and precision.
Patek Philippe watches are defined by balance and understatement. Even small deviations in thickness, taper, or curvature can affect how the watch wears and looks on the wrist.
We focus on correct proportions, natural curvature, even weight distribution, and a refined finish — so the strap supports the watch rather than announcing itself.
Pricing & Payment
What does an INRO bespoke strap start from?
Bespoke straps start from:
- £425 in Calf, Suede, or Silk
- £575 in Alligator
Pricing depends on specification and material choice.
What this includes
- Consultation-led guidance and curation
- A fitting-led approach
- Focus on comfort, balance, and longevity
This is not an upgrade — it is the foundation of the service.
Why does bespoke cost more than off-the-shelf?
Because it is made for a specific watch and a specific wearer.
In practice, bespoke involves planning, pattern work, hand shaping, construction, and finishing— with attention to proportion, taper, thickness, hole placement, and hardware compatibility.
It is precision craft, not mass production.
When is payment required?
Payment is requested after your consultation, once all details have been agreed.
Why this timing works
At this stage:
- Design and materials are confirmed
- Specifications are fully clear
- There are no assumptions or surprises
Full payment then confirms your commission, secures materials, and allows work to begin.
Next Steps & Delivery
What happens after my consultation?
The process is simple and guided.
What follows
- Measurements and proportions are confirmed
- Design and materials are agreed
- The strap is handcrafted
- Final fitting ensures the strap sits correctly
We handle the technical detail so nothing feels rushed or uncertain.
How long does a bespoke strap take?
As a general guide, most bespoke watch strap commissions are completed within several weeks.
Lead times vary depending on:
- Material choice
- Complexity of the commission
- Current capacity
We’ll advise a realistic timeframe during consultation, so expectations are clear from the outset. We confirm timing at consultation once specification and capacity are clear.
Can I commission multiple straps for one watch?
Yes — many clients do.
Once your fit and pattern are established, additional straps can be created efficiently, allowing you to build a considered rotation around a single watch.
Fitting
Do you fit the strap to my watch?
Yes. Fitting is integral to our service.
Fitting is carried out by appointment at our Marylebone atelier, either during consultation or at final collection.
It is carried out with appropriate care — particularly for vintage watches and original hardware — to ensure security, balance, and a clean, scratch-free result.
Can I fit the strap myself?
We don’t recommend it, especially for valuable or vintage watches.
Incorrect tools or technique can easily cause damage. Professional fitting ensures the strap is secure and the watch is protected.
Fit & Wearability
Why do so many straps feel acceptable, but never truly right?
Because most straps are designed to be acceptable, not precise.
Common issues include:
- One hole too tight, the next too loose
- Incorrect strap length or excess tail
- Off-centre clasp or buckle positioning
- Stiffness or imbalance that never truly settles
These issues rarely feel dramatic — but they’re persistent. Over time, they distract from the wearing experience and often lead to the watch being worn less.
Bespoke corrects the cause, rather than asking you to tolerate the symptom.
Why does my watch keep rotating or never sit straight?
Rotation is almost always a fit and balance issue.
Strap length, hole placement, wrist profile, clasp position, and watch weight all interact. When these elements are misaligned, the watch has no natural resting point — so it moves.
Bespoke allows these variables to be corrected together, so the watch sits where it should without constant adjustment.
Why do so many Cartier deployant straps never quite settle on the wrist?
Many Cartier watches are designed around deployant clasps that require a precise, made-to-measure fit.
When worn on standardised strap sizing, the result can be an off-centre clasp, excess length, pressure points, or a watch that never quite settles on the wrist.
At INRO London, we recreate that made-to-measure intent locally through careful consultation and considered shaping — so the strap wears as the watch was designed to.
Should a leather strap feel comfortable from the first wear?
They shouldn’t — but many do.
A painful break-in period is rarely a feature of leather itself. It’s usually the result of how a strap has been designed, layered, and finished. Most standard straps are made to generic dimensions, often with stiff padding and heavy glues that resist wrist curvature.
At INRO, our straps are designed to be comfortable from the first wear, using naturally flexible leathers, controlled thickness and taper, and shaping that supports how you actually wear your watch.
In short: a proper bespoke strap shouldn’t require weeks of discomfort to feel right.
Aftercare
Do your bespoke straps come with a guarantee?
Yes. All INRO bespoke watch straps are covered by a two-year craftsmanship guarantee.
This covers workmanship and construction integrity under normal wear, including stitching and structural assembly. Normal ageing, patina, moisture exposure, and accidental damage are not considered faults.
If an issue arises, we’re always happy to assess the strap and advise on repair or adjustment where possible.
At INRO London, this guarantee reflects how we approach the work — with accountability for construction, not shortcuts or compromise.
Do you offer adjustments or repairs?
In many cases, yes.
We assess each strap individually and will always be transparent about what’s possible based on construction, wear, and condition.
How long should a quality strap last?
Leather is a natural material that will soften and develop character over time.
For best longevity, we recommend avoiding prolonged exposure to moisture, allowing straps to rest between wears, and gently wiping after use. Care advice is always tailored to your chosen leather and wearing habits, and we’re happy to advise or assess a strap at any stage of its life.
