Installing a Speedmaster Type Bezel
This is a guide for the Do-It-Yourself installation of a bezel on a Speedmaster.
Please note this guide will focus on installation of a caseback using our 3D-printed tools and a dedicated crystal press where necessary.
01
Prepare Your Toolset
Check to make sure you have the Round Tool component of our Toolset for Omega Sports Watches.
02
Prepare Your Press
(A Press Is Generally Needed For Pre-3861 Bezels)
The installation can be performed with both premium and inexpensive crystal presses, such as this $600 Bergeon 5500 or this $20 generic set.
03
Select Press Dies
We generally find it easiest to use a 42mm die for the bezel side, and a 38mm die to support the caseback.
Note: It is generally a good idea to support the watch head with a die on the caseback so force is not transmitted through the crystal.
04
Install Press Dies
Our standard installation process utilizes the dies in the configuration shown. Inexpensive presses may exhibit a lack of parallelism, which tends to make installation slightly more difficult, but not impossible.
05
Remove Bezel
Utilizing the round tool, press the chisel tip into the gap between the bezel and the lugs. The chisel tip is slightly oversized, and pressing it into the gap will gradually pop the bezel out.
No levering is necessary.
06
Align Your New Bezel
Place your bezel on the midcase, and be careful to ensure that the graduations are properly aligned with the minute marks.
07
Press Bezel Into Place
If the bezel partially mounts, there is likely poor parallelism between dies. The watch head should be delicately rotated and re-pressed until the bezel secures.
Bezels for 3861 watches can generally be installed by hand, but installation with a press is possible as well.
08
Enjoy Your New Bezel
Double-check the bezel to ensure it is fully seated and properly aligned. If so, you're done! Congratulations, and enjoy your Speedy in good health!
