Just swapped out a bezel insert on a GMTmaster. Certainly not as straightforward as some suggest.... but.... I eventually got there. The bezel seems to have engaged the click spring okay, but it does feel slightly tighter than previously on rotation. The circular washer was not warped in any way and all surfaces were clean. Just wondering for the future however, is there any benefit to be had in adding a very miniscule amount of light grease or lubricant. Grateful for any views or advice - many thanks!

Bezels definitely need lubrication, Rolex uses 'fomblin, grease for this. Just a little bit in the teeth of the bezel.

Hi Bas,

Only at the teeth, or also a bit on the ring that holds the bezel?

Thanks for your advice here.

Small amount in the teeth, nothing on the washer or inner snap lip of the bezel or midcase. It's mainly just to reduce wear on the teeth and click spring.

Krytox grease can also work in a pinch but Fomblin is one grade thicker. If you can find Fomblin then it's your best option.
