Inspired by the Sextant, and other 17th Century navigational instruments used by John Harrison in solving the longitudinal problem, this dual-zone timepiece straight forward, ergonomically designed for easy read which is the signature of all Torgoen watches. With a vintage design and bold look, this time piece incorporates two independent time zones one of which is represented by an additional hand that makes one revolution every 24 (rather than the normal 12) and therefore has a display in 24 hour (military) format.
