Unlike the precious metals used in H. Moser’s regular timepiece collection, the Endeavour Dual Time Special Edition has a case of polished grade five titanium (used in very few H. Moser special editions) with a diamond-like carbon (DLC) treatment. Grade five is the highest grade of titanium used in watchmaking. It is not only very hard, easy to wear, hypoallergenic and very light, but it is also the only grade of titanium that may be polished like a precious metal or stainless steel. As such, the Endeavour Dual Time Special Edition, like other H. Moser timepieces, enjoys specific finishes and decorations on its various surfaces and edges, including mirror and hairline finishes. The diamond-like carbon treatment gives the Endeavour Dual Time Special Edition an understated and mysterious deep black surface, and it helps protect the case further from scratches, making for a timepiece that is suited to daily use.
