Bezel

12-Hour GMT Bezel Collection

Meridian & Crosswind
Turn your Black Bay 58 into a dual-time tool—with nothing but a bezel change.

Most owners don’t realise the Black Bay 58 can track a second time zone. With a 12-hour bezel, it can—no movement change required.

This collection was built for that purpose.
Two bezel options. One function: clean, mechanical GMT tracking.


Meridian

A high-contrast, bold alternative for those who want their bezel to stand out.
Cobalt blue with gold GMT markings, designed to echo the clarity of vintage flight instruments—without leaning into nostalgia. It brings warmth, colour, and legibility in one confident spec.


Crosswind

Matte black with silver markings for a more restrained look.
Crosswind blends seamlessly with the original Black Bay aesthetic, offering discreet GMT functionality that keeps the core design language intact.


Both bezels are precision-machined in steel and designed exclusively for the Black Bay 58 case profile. Installation should be carried out by a qualified watchmaker.


Additional Details

Each bezel is fully reversible—allowing you to return to your original configuration at any time, without compromise. Flexibility, built in.

Disclaimer
Steel Reef is an independent company and is not affiliated with Tudor or any other watch brand.

While home installation is possible by carefully following the steps below, we strongly recommend having this work carried out by a professional independent watchmaker experienced in bezel assembly. Authorised retailers for any specific watch brand will not undertake this modification.

Bezel Removal Steps:

  1. Tape around case sides and lugs to protect against scratches.
  2. Insert the case knife at 7 o’clock on the case side, between bezel and case.
  3. Use controlled rocking motion to gradually lift the bezel-do not pry or force.
  4. Once loosened, gently lift off bezel and set aside.
  5. If dislodged during bezel removal, retain the click plate and all four spring plungers, and reinstall them carefully in their original positions.

Insert Removal & Replacement:

  1. To remove the original insert, flip the bezel over and use a press tool with a flat nylon die to push the insert out from the underside.
  2. To install a new insert, align it correctly and press it into the bezel from the topside using the same press and an appropriate die.
  3. Ensure the die does not contact or stress the insert edge; use only flat or shallow concave dies that match the insert’s shape.

Bezel Installation Steps:

  1. Lightly grease the new nylon ring and insert into bezel groove.
  2. Clean all parts; check click springs and plate for wear.
  3. Reinstall spring plungers and click plate.
  4. Align bezel with triangle at 12 o’clock. Ensure springs remain upright.
  5. Use press with flat nylon die to apply slow, even pressure until bezel snaps on.
  6. Confirm:
  • Secure fit (no rocking or gaps)
  • Smooth rotation
  • Accurate alignment at 12

Important Notes:

  • Do not press the bezel on by hand. Always use a proper press.
  • Do not lubricate excessively-just a minimal film.
  • If you are not a trained technician, we recommend having your bezel installed by a professional watchmaker familiar with Tudor friction-fit systems.
  • Any modification to your watch-including bezel replacement—may void the manufacturer’s warranty. Proceed at your own discretion.

Please note: While our products are designed for user-friendly installation and Steel Reef is not liable for any potential mishaps during the process, we always recommend seeking expert assistance for the best results. Additionally, be aware that installing our products may void any active warranties or guarantees on your watch.

We are not affiliated, associated, endorsed by, or in any way officially connected with any watch brands. Our parts are aftermarket accessories, designed with precision, that may be compatible with and fit a variety of watch models.
