JeanRichard/Lorenz Model 60 Diver Help

Hello All,

Wanted to request some help on another forum if that’s alright. I picked up a Lorenz diver - looks to be a rebranded JeanRichard 60.

I removed the bezel to clean it, but did not find a retaining spring. When I put the bezel back on, it snaps nicely to the case, however, the bezel spins too loosely.

Does this watch have a particular size for a bezel spring or maybe a bezel gasket? Any other info about this watch would be helpful!

Thanks!
