This has several unusual features, including a snail cam instead of a fusée, a chain with ruby links, push button winding and a barrel with sapphire inserts.

And instead of a traditional chain, this chain uses ruby inserts for minimum friction and finer tolerances.

Winding is accomplished by pressing a button in the case at nine o’clock, which transmits the force to the barrel on the same plane
Inside the barrel, a pair of sapphire plates sandwich the mainspring, which minimises wear inside the barrel over time. This is similar to what Denis Flageollet at De Bethune devised several years ago for the Super Sport watch.
The Logical One also sports a high-end movement finish, including an unusual double-angle anglage, which comprises of two parallel, polished bevels on the bridges. The case size is 43 mm and available in red gold or platinum. – SJXBack to top.
