"Nightfall" Black & Black Precision GMT Bezel

Installation Video

We strongly recommend having this work carried out by a professional independent watchmaker.

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.
