Underneath the dial a newly developed Remontoir movement, the caliber LANG & HEYNE Cal. VI-I, is responsible for the accurate display of the time.

Through the sapphire glass case back it is obvious, that the main parts of the movement were manufactured of an entire new material – titanium. Commonly used for manufacturing cases, it has found its way into an unusual use.

The use of titanium has presented entirely new challenges to the master watchmakers of LANG & HEYNE. In order to meet the very high demands on the quality of the technology but also on the aesthetics, it was necessary to adapt and modify traditional skills and processes.

Medium-hard titanium of purity grade 2 is used to manufacture the movement plate, gear bridge, lever bridge and balance cock. To create a matte sheen, the graining is achieved by blasting with ceramic beads which, unlike glass beads, do not shatter when they hit the material. For brass frame parts, the polished chamfers are then pressed on with the smoothing steel. This is not possible with titanium. It has unfavorable friction behavior, which would cause the spinning tool to leave cracks. So here the chamfers have to be polished very laboriously with wood and polishing paste.
