Founded in Geneva in 1883, Alpina has built its identity around robust, legible and technically serious watches for active use — originally for alpine sports, later for aviation. The Startimer Pilot is the brand's most direct expression of that philosophy: a pilot's tool watch that draws on the long tradition of large-cased, highly readable cockpit instrument watches and makes no concessions to decorative detail. The AL-725N4S6 is the navy blue variant.

Reference AL-725N4S6 is a 44 mm stainless steel automatic chronograph, 14.5 mm in thickness, with a brushed case and screw-down crown. The navy blue dial carries large luminescent Arabic numerals and a railway-track inner minute scale, with a bi-compax layout: a 30-minute counter at twelve and a 12-hour counter at six, with a central seconds hand and a date window at three o'clock. At its heart beats the Alpina Calibre AL-725, based on the ETA Valjoux 7750, with a 46-hour power reserve. The scratch-resistant sapphire crystal carries anti-reflective coating. The fixed stainless steel bezel keeps the case clean and purposeful. Water resistance is rated to 100 metres. The watch is supplied with two wearing options: the original brown leather strap with white contrast stitching and a folding deployant clasp, and an additional brown leather strap with a stainless steel pin buckle.

This Alpina Startimer Pilot Chronograph is in good condition and comes as a full set with servicehistorie.
