Beautiful. Sporty. Horological Magic. The Zenith Chronomaster Sport (reference 03.3100.3600/21.M3100) is a popular "grail" timepiece for a reason. The tri-color subdials are both beautiful and instantly recognizable. The glossy dial, beautifully finished case and bracelet, and ceramic bezel all come together to make a striking, sporty timepiece with 100m Water Resistance. But the star of the show is the El Primero movement. Yes, the El Primero movement has a storied heritage as the original movement inside the Rolex Daytona. But this El Primero has awesomeness all it's own. COSC certification. 36000 beats per hour. 1/10 of a second accuracy with a chronograph hand that sweeps around the dial once every 10 seconds, and is one of the most wearable chronos out there at a slim 13.8 mm with a curved lug profile that slips easily under a shirt cuff. This watch is the whole package: technological wonder and beauty all in one. This example is in great condition as pictured, and comes with watch, full links, an additional Horween Leather racing-inspired strap, inner and outer boxes, travel case, instruction manual, and paperwork for a recent full factory service.
