On request, the watch can be fitted with the PB10 or PB30 (central seconds hand) calibers in their various decorated or semi-skeletonized versions, optionally complemented by a screw balance or a swan-neck regulator.
Those interested in an automatic can opt for the PB51 caliber with central seconds hand and micro-regulation.
The price of the watch includes a strap made to the customer’s individual wishes. This covers the choice of leather color, the color and style of the stitching, including the type of thread (synthetic or natural linen thread). Hypoallergenic leathers tanned exclusively with natural vegetable tannins are used as standard. The options also include individually adjusted lengths of both parts of the strap.
The price also includes personalization of the relief inscriptions on the caseback and the option of replacing the relief company emblem on the crown with the customer’s monogram.
On request, the classic wooden box can be replaced with a more practical genuine leather “travel” case.
