About the Excalibur Spider family
Excalibur Spider is the most technical branch of the Excalibur, with both the case and the movement heavily open-worked so that the structure of the watch is visible from the side as well as the front. Cases are made in light materials such as titanium, carbon and ceramic, and several models were created with partners from the car world.
The references in this catalog include skeleton and tourbillon versions. Because the case is open, check for dust and damage between its parts, test every function, and make sure the straps and full set are present.
