Serica's new 7505 Olive Field Chronometer makes 35mm a strength

The May 2026 7505 puts a COSC automatic movement, olive enamel dial and 200m resistance in a compact case.

The Serica design draws on the practical principles of military field, pilot or naval watches: clear at-a-glance reading, restrained surface treatment and durable construction. This specific reference was presented in 2026; it is not a claim that the watch was issued to armed forces.

The stated specifications include reference 7505-2, case diameter 35 mm, movement Soprod M100 automatic, COSC, power reserve 42 hours, water resistance 200 m. These are manufacturer or contemporary launch specifications rather than measurements taken by Chronolume.

Design-wise, the interest lies in the balance between recognisable equipment heritage and a modern wristwatch. The resulting watch is useful to collectors who appreciate military-derived industrial design without requiring a replica of a historical service watch.
