Haveston Service Watch Dial Coasters - Set C

An original Haveston product design, the Service Dial Coaster series features a selection of the most archetypal vintage military watch dial designs, revered by collectors for their history, aesthetic and service. Constructed from detailed heat-resistant silicone, each 4mm-thick, 90mm-diameter coaster closely conveys the character of its namesake design, and serves perfectly as a soft landing for your timepiece or beverage. Set C includes the following dials: “Fab Four” 924-330 - 1973 Commissioned by the U.K. MOD in the 1970s, it utilized a readily available commercial ETA-7733 Chronograph movement and was illuminated by tritium paint. Departing from previous Lemania-powered monopusher movements, the dual pushers allowed stop and resume of elapsed time. A-7 Aerial Navigation - 1935 Commissioned for the US Army Airforce in the 1930s, the A-7 monopusher chronograph had a huge 49mm case with a deliberately 40-degrees-offset, non-illuminated dial for easier reading while holding the flying yoke. Trench - 1918 With distinctive WWI radium-illuminated “Gothic” style numerals, chronographs of this era were often found in monopusher pocket watch form. For efficient legibility, Roman numerals were being phased out in preference of Arabic, with black enamel dials for higher contrast. Airforce Tri-Compax - 1944 A dual-pusher, radium-illuminated chronograph, mainly issued to aircrews. Unlike most bi-compax chronographs of the period, the addition of a third subsidiary register allowed the recording of elapsed time beyond an hour. A now-familiar and optimum stage of chronograph dial design.
