SIZING GUIDE (BRACELET LENGTH)
UPDATE (October 2026):
1) With more than three thousand sold already, we are really able to dial in the sizing guidance now. ALL of the below info has been checked, confirmed, and verified. This update will serve as additional info to help you to find the exact size AMB-001 bracelet for you and your watch.
2) Only order a Mid-Size AMB-001 if your wrist measures -- using our detailed measuring methods outlined below -- 6.7" (17.0 cm) or less. If your wrist is 6.8" (17.25 cm) or larger, at any time, then please order a Standard length AMB-001.
3) We cannot stress enough how important it is for you to follow our measuring methods. You and we must work toward a shared standard in order for our sizing guidance to be accurate. Please use one of our two proven measuring methods:
MEASURING METHOD A - If you have an existing bracelet for your watch
MEASURING METHOD B - If your watch does not currently have a bracelet
UPDATE:
1) PLEASE NOTE: For Grand Seiko watches with the modern 44 GS case, you will lose 1 to 2 holes of adjustability. In other words, STANDARD SIZE = 6.5/6.6" (16.5/16.75 cm) to 7.1/7.2" (18.0/18.25 cm).
2) PLEASE NOTE: For most JLC Reversos (excluding the largest models such as the Grande Reverso 976 or the current Chronograph) you will lose between 2 to 3 holes of adjustability. In other words, STANDARD SIZE = 6.4/6.5" (16.25/16.5 cm) to 7.0/7.1" (17.75 cm/18.0 cm).
3) Basically, watches smaller than the 41 mm 2254.50 SMP will make our bracelets wear shorter usually by approximately 1 to 3 holes of adjustment, which equates to 0.1/0.3" or 2.5/7.5 mm. In certain circumstances, such as with the smaller size Reversos, you may lose up to 3 holes of adjustment.
If you have any questions at all about sizing, please contact us here prior to finalizing your order. We are happy to help you find the perfect AMB-001 bracelet for you and your watch. Thank you.

SIZING GUIDE (BRACELET LENGTH)
LET'S MAKE IT SIMPLE ...
IF YOUR WRIST SIZE IS:
- 6.2" to 6.8" - (15.75 - 17.25 cm) = MID-SIZE
- 6.7" to 7.3" - (17.0 - 18.5 cm) = STANDARD
- 7.2" to 7.8" - (18.25 - 19.75 cm) = LONG
- 7.7" to 8.3" - (19.5 - 21.0 cm) = EXTRA-LONG
PLEASE NOTE: Our bracelets are designed so each wearer will have 1 - 2 holes for adjustment. (The full range of adjustment is provided so each bracelet size can accommodate a range of wrist sizes.) Out of over three thousand customers thus far, we have found that not a single person has needed more than 2 holes to adjust up, in real world application.
WHERE TO MEASURE YOUR WRIST:
1. PLEASE NOTE: Please take the time and effort to measure your wrist carefully. We have found that people tend to either overestimate or underestimate their wrist size. Please take the extra time and effort to be precise with your measurements, as we are very confident about our sizing guide.
2. We have found that measuring one's wrist with one hand will give you uneven results. If possible, please have a second person help you to measure your wrist carefully in the following way:
Please measure your wrist without pulling or placing any tension on the tape measure. (Old tape measures, we have found, will almost always be 1/4" or more off due to stretching! We were surprised to learn this but it is true.)
We have found that pulling even slightly on the tape measure will compress the flesh of the wrist a small but critical amount. A little bit of compression may seem insignificant IRL, but in terms of fitment for our AMB-001 bracelet, which comes down to a matter of millimeters, 1/4" can be a determining factor for choosing the correct size. For example, a 7.0" wrist and a 7.25" wrist will potentially need different size bracelets.
AMB does not take responsibility for orders placed based on poor measurements on the customer's end. If you have any questions please contact us prior to finalizing your order. If you can write "WRIST SIZE HELP" in the title, we can better address your concerns.
3. PLEASE NOTE: Any bracelet that has been test fit, or otherwise shows signs of sizing or use, cannot be returned for a refund. If you have any final questions regarding sizing please contact AMB before placing order. Thank you.
WATCH CASE SIZE & HOW IT AFFECTS SIZING:
4. The above wrist sizes/fitments were calculated using a very "standard" lug-hole to lug-hole measurement of 43.0 mm, which can be found on well-known watches such as the neo-vintage Omega Seamaster Professional 300 m (41 mm SMP).
4a. PLEASE NOTE: If your watch is LARGER between the centers of the lug holes compared to the above mentioned SMP 2254.50, the bracelet will wear slightly larger.
4b. PLEASE NOTE: If your watch is SMALLER between the centers of the lug holes compared to the above mentioned SMP 2254.50, the bracelet will wear slightly smaller.
5. We measure from center-of-lug-hole to center-of-lug-hole for our sizing purposes.
6. PLEASE NOTE: The often used exterior LTL (lug-to-lug) measurement seen on watch enthusiast forums does not apply here, because it is not used to calculate bracelet fitment.
ADDITIONAL INFORMATION:
7. Personal preferences for how tight or how loose one chooses to wear their watches will also affect final fitment.
8. PLEASE NOTE: All of our measurements were made with a snug, but not restrictive bracelet fitment, aka a "Watchmaker's Fit" on a bracelet worn on the actual wrist (not the "wrist bone," or Ulnar Styloid). You should only be able to insert a single finger tip underneath your bracelet with a watchmaker's fit.
9. If you prefer a looser fit, you will have to factor in an additional 1/4" up to 1/2" (6-12 mm). Please note, we cannot determine how much extra room you want. If you like to wear it loose, please measure your wrist accurately, as described here in this Sizing Guide, and then add 1/4" (or slightly more).
