Details & Specifications
DESCRIPTION
The Mk.2 chronograph case attempts to overcome significant engineering challenges Hajime Asaoka faced in the construction of the Chronograph 1 - which leveraged the Seiko NE86 that was by itself a thick movement at 7.65mm - and takes in stride collector requests for a thinner case. With the new Mk.2 case, Hajime Asaoka overcame the limitations by incorporating a design technique from the 1930s - to make the thickness of the movement imperceptible on the exterior. The Mk.2 is now a three-part case that has a much thinner visual profile, but is also built more robustly and allows for better repairability. In terms of comfort, the lugs shape and position have been newly adjusted to ensure the same comfortable fit as before.
