he new Ref. 7505 is offered in three enamel dial variations. The all-new Minute Critical Dial brings a bolder, more immediate reading of the full 60-minute scale, available in Black and Olive Green. The TXD dial completes the collection with our beloved take on the Tuxedo dial.
While fully rooted in Serica’s ethos and design language, the Ref. 7505 brings an entirely new expression to the line-up. Smaller in size, yet bolder in many ways, it introduces a new case design with curved inner lugs and no chamfers, alternating finishes with polished sides, and half-spheres on the bezel, extending the dial’s cardinal markers.
Bringing a new watch into an existing collection means remaining true to what defines it. The Ref. 7505 builds on the established Serica field watch language, retaining its wide flat-top brushed bezel, enamel dial, signature Bonklip bracelet, and the hard-wearing professional specifications that define the collection.
The Ref. 7505 introduces a fully redesigned Bonklip bracelet, with curved end-pieces, squared polished links, and a stronger taper, now fitted with the new Safe-Lock clasp. Seamlessly integrated, it offers added security while allowing the bracelet to be worn slightly loose.
