The Merlin rotary engine, produced by Rolls-Royce, powered one of the most legendary aircraft of all time: the P-51 Mustang. And its from this fighter plane Techne Instruments' 1940s military-inspired watch gets its name. A beautiful minimalist-field watch made from 316L stainless steel, the 246 is powered by a Seiko-built quartz movement, has anti-shock and -magnetic properties, has a 36-month battery life, and is water-resistant to 50 meters. And the luminous markings on the no-nonsense dial make for easy viewing in any light. For a straightforward and handsome time-keeper, you can do no better.
