The Grande Classique 100 Diamonds features an ultra-slim case – only 4.60 mm. This profile has been achieved through the particular design of the case, which incidentally Longines has patented, whereby the back incorporates the lugs for the bracelet. 

The timepiece is fitted with a quartz movement and is water-resistant to 30 meters. It is fitted either on black alligator straps with buckle or on steel bracelets with folding safety clasp and push-piece opening mechanism.
