At first glance, this watch exudes an extremely rough style, revealing an undeniable sporty "big guy" style. It is undoubtedly a sports watch and tool watch. But when you flip the watch over, the scene before your eyes is astonishing. Adapted from the extremely classical movement of Lemania 2310, meticulously polished and even bearing the Geneva Seal, this highly complex movement with numerous parts is sealed with a large screw-in case back, creating a visual effect akin to peering into a secret underwater world, mirroring the boldness on the front with the refined pedigree of the movement. The strong contrast encapsulates the personality of the founder. Mr. Chung Yam Lun once said: Those who can master the 2310 movement well, the first is Patek Philippe, and the second is Roger Dubuis. The fame of the 2310 movement lies in its long service to giants like Patek Philippe, Vacheron Constantin, and Breguet, and it is also the prototype of Omega's moon landing 321 movement. The prices of early Roger Dubuis watches equipped with Lemania movements have soared in the past two years, and the sports models have attracted many serious collectors. This SE46 model comes in two versions: a regular steel version limited to 888 pieces, and a steel case with a platinum bezel limited to 280 pieces. The one being shared today is the latter, extremely rare. Although the 46mm diameter may not be very wrist-friendly for those with smaller wrists, imperfections aside, at this price point, having a watch with such a movement is already a great value. The watch being shared today is in mint condition, almost perfect, running well, and comes with a one-year warranty from our workshop.
