Bezel lubrication

[strafer_kid]

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!
