The price of the watch includes a strap made to the customer’s individual wishes. This means a choice of leather color and of stitching color and style, including the type of thread (synthetic versus 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 to replace 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.
