Each year we produce a new series of designs. The watches are initially released in a numbered edition of 100 pieces (each watch is numbered on the back of the case). If a design sells well then we update the design (to distinguish it from the limited edition version), and reissue it as part of our permanent collection. From time to time with the most popular models we produce a variation on the design. This is called a Special Edition and is generally produced in smaller quantities and available for a limited period.
