The Pulsion collection successfully replaced the Easy Diver collection in 2012 SIHH trade exhibition with 2 variants, one with tourbillon and the other with a chronograph.The current lot is believed to be part of a 20-piece limited edition, where 10 pieces were allocated to the Japan market and the remaining to the US market. Differentiating from regular pieces, the bezel is white compared to the regular black bezel. Complementing with the white rubber strap, the watch commands hefty wrist presence while having a strong contrast to the DLC-coated titanium case.
