The price of the watch includes the production of the strap according to the individual wishes of the customer.

You can choose:

- the color and texture of the leather, the color and style of stitching, including the type of thread (synthetic versus natural linen). Of course all used leather is strictly antiallergic - made entirely of natural tan.

- length and profile of both strap parts.

The price also includes the individualization of the relief descriptions of the watch on the lid and the possibility of replacing the relief corporate sign on the crown with the customer's monogram.

On request it is possible to replace the classic wooden box with a more practical "travel" case made of genuine leather.
