摘要
The watch case includes glass (5) set into an Gold rim (1) with a case (2) and an Gold back (4) secured by screws (6) into the strengthening structure (3), which is of composite plastic and moulded on to the Gold element of the case (2). The rim (1) and case (2) are held together by screws (7) which, like those through the back (4), may be inserted through reinforcing washers if the plastic is insufficiently rigid. ADVANTAGE - Cost and weight are reduced by use of a min. amount of gold, and moulding which eliminates complex mfr. and assembly of strengthening elements.
