Gonna be making a habit of switching straps on my M52. Do I purchase the Bergeon 6767-F or the Bergeon 6767-S. It's all new to me, I come from the school of using a knife, so unsure which Bergeon I need. Many thanks.

I'd suggest the F (for fine tip). It's unlikely it'll ever be too small, but entirely possible the S may be too big to fit into those extra-tight spaces between lug/bracelet.

Get the 6767-F.

I recently purchased a used M52 and a 6767-F. Easy strap/bracelet swaps using the tool.

I also bought an inexpensive bracelet tool from Amazon that works with the 24mm bracelet on the M52.

I am going to disagree with the others. I think the standard S model would be better for working on relatively thick straps. I have both and I would use the S every time on a watch like this. The F is definitely required for working with bracelets.
