Need help measuring? Open the sizing guide
1. Find your watch's lug width
The lug width is the gap between the two lugs where the strap attaches. Most watches list this in their specs — common sizes are 18mm, 20mm, and 22mm.
If your watch isn't listed: measure the gap with a millimetre ruler, or note the existing strap's width near the spring bars. Round to the nearest whole millimetre.
2. Measure your wrist
Wrap a piece of string, ribbon, or paper strip around your wrist where the watch sits. Mark where the end overlaps. Lay it flat and measure the marked length in cm or inches.
Tip: Measure with a comfortable fit — not too tight. The strap will sit at this length, with the buckle on the underside of your wrist.
3. Find your strap length
Each strap length on this product is shown as two numbers, e.g. 75/115mm: the buckle-side cut and the tail-side cut, both measured from the watch lugs. Use the calculator below to find your size — it reads the actual sizes available for this strap and recommends the closest match.
Calculate your strap length
Enter your wrist size and your watch's lug-to-lug distance — we'll recommend the matching strap length and you can apply it with one click.
This is a recommendation only. Custom straps are not fully refundable. To protect against fit issues, measure the short and long pieces of your current best-fitting strap with a ruler and use those numbers if they differ from the recommendation.
Need a custom length not on the list? Pick the closest size and write your exact requirement in the Notes field at the bottom of the configurator — we cut to spec. The buckle has multiple holes, so being within a few millimeters of the calculator's recommendation is fine.
Upload a clear photo of your buckle (top + side view if possible). JPG, PNG, HEIC or WebP, up to 20 MB.
Length note: This single-fold clasp may require us to modify the strap length to suit the clasp mechanism — we'll set it for a correct fit.
We need this to size the bund pad correctly. Measure the watch case from edge to edge (not including the crown).
We do our best to match the thread to your leather, but exact matches aren't always possible — natural variations in leather and thread dye lots mean the result may be very close, not 100% identical.
Custom strap length selected — please tell us the exact length here (e.g. 110/175 mm = 110mm keeper end / 175mm tail end).

Common questions
Your Cartier clasp
Will this strap work with my original Cartier deployant (folding) clasp?
Yes — that's exactly what we build for. Choose "Build for my Cartier deployant" in the configurator and we cut both strap ends to seat in your original clasp, so you keep the buckle you already own.
Most aftermarket straps ship with a pin buckle that orphans your Cartier deployant. We don't. For listed Tank Solo references we already know the clasp clamp width — nothing to measure. For an unlisted or vintage reference, we'll ask you for the clamp width (with a simple measuring guide) before production.
What if I don't have the Cartier deployant, or want a spare?
We can source a Cartier-style deployant clasp for you — pick one of the Cartier-style deployant options in the configurator (Gold, Stainless steel, or Rose gold, +$30). You can also choose a standard pin buckle from our buckle options if you prefer a traditional buckle-and-tang strap.
Reference & fit
How do I know which Tank Solo reference and lug width I have?
Tank Solo sizes and lug widths: Small — 17mm (W5200013 / W5200005); Large — 20mm (W5200014 / W5200025); XL — 23mm (W5200027). Just pick your size in the configurator. Vintage or unlisted Tank Solo references vary — email a side-profile photo and we'll confirm the lug width before you order.
Does the strap use Cartier's quick-release system?
The Tank Solo uses standard spring bars — our straps ship with the correct spring bars for your reference and install with a normal spring-bar tool. If you're unsure of your reference, send us a side-profile photo and we'll fit the correct bars.
I have a vintage or unlisted Cartier reference — how do I order?
Email us a side-profile photo of your watch showing the lug-to-case joint, plus the case-back if the reference is printed, and add any notes in the configurator. If you're using your own deployant, measure the internal clamp width where the strap seats (we'll send a guide) and add it in the notes. We confirm fitment within one business day before cutting.
My wrist is larger or smaller than standard — can you accommodate?
Yes. Every strap is cut to your measurement, with custom length from 5.0" through 12" wrist at no extra charge — long-wrist Tank Solo owners are a size Cartier's own straps don't offer. Use our Bespoke Fit Calculator, or enter your wrist measurement in the notes and we'll size it for you.
Order & policy
How long from order to arrival?
Two to three weeks production from our workshop, plus shipping. Priority shipping is available at checkout. We ship worldwide from Vancouver, Canada.
What is your refund policy?
Because each strap is made to order, we generally cannot offer full refunds for returns based on preference. If your strap has a manufacturing defect or a fit issue caused by our error — when we confirmed fitment with you in writing — we remake it. Contact customer service with any concern and we'll make it right.
