Thanks Jeff! The serial number is 44760, still clearly visible. I am quite sure it is chrome plated. The lug ends have wear that is consistent with plated metals and not solid stainless.

I'll attach a picture that shows the wear on the lugs (and the serial nr too).

: Yes, this one looks like a Reference 3641. I assume that you are
: confident that it is chrome-plated, rather than stainless steel?

: Seems that we see a lot of them with the "stick" style
: hands, but the catalog shows them with the dauphine hands, like
: yours.

: It's a nice looking watch!! Just for our database, can you please
: send me the full serial number?

: Many thanks!!
