Introducing: Serica Downsizes Its Field Chronometer With The 35mm Ref. 7505

Inside the case is the SoProd M100 movement, which is COSC-certified for accuracy, making it a Field Chronometer in both name and function. The caliber runs at 4Hz, is self-winding, and has a 42-hour power reserve. According to Serica, it also has a decorated plate with Côtes de Genève, and while there are no photos of the caseback, I would assume it is still a closed caseback like its big sibling. 

Then there’s the final major update: the watch comes with a redesigned Bonklip bracelet, featuring curved end pieces, squared, polished links, and a stronger taper. It’s also been fitted with a new Safe-Lock clasp, which is more secure but also allows the owner to wear the watch a bit looser if they want. The bracelet comes in three sizes.
