A professionally customizable timepiece includes a primary casing including a movement and configured to operate independently as a timepiece, and a secondary casing having an interior space for receiving the primary casing and further design elements. The secondary casing completely encloses the interior space and can be opened without tool for placement of the primary casing and/or design elements into the interior space or to remove them from there. The secondary casing includes a sight glass and is configured to secure the primary casing at a selectable position in the interior space.
