Legacy Black

A timely meeting of craft and contemporary design

Legacy Black
 

PRECISE ACCURACY AND UP-TO-THE-MINUTE AESTHETICS

Our illustrious founder, Thomas Mercer, would no doubt approve of this sleek, matt black design. Throughout his career, his thinking was far ahead of its time.

The Legacy Black marine chronometer features a case displaying a distinctive asymmetrical body of stainless steel with a Diamond-like Carbon finish. Its dial combines Geneva stripes (Côtes de Genève) and black electroplating. The mechanism, visible through the dial apertures, has a bi-colour finish blending All Black and Rhodium plating. Importantly, the movement remains horizontal, regardless of a yacht’s motion at sea.

CRAFTSMANSHIP WITH A CUTTING-EDGE

The Legacy Black combines mechanical precision with the most modern materials. Its AISI 316 stainless steel body is treated with Diamond-like-Carbon, a high-tech coating that gives metal surfaces the hardness and wear-resistance of diamonds. Another strength is the drive mechanism, a mechanical spring with a fusee-and-chain system. Like the spring escapement, these inner workings are visible for all to see.

Material

The case is bi-colour with Polished and DLC coated stainless steel.

MEchanism

calibre tm0801

The mechanism breaks new ground while retaining the classic elements of a pure marine chronometer. With a symmetrical layout and skeletonised plates, the detent escapement has been moved from its traditional place on the back plate to a new position where it can be viewed through the dial apertures. The gimbals suspension allows the mechanism to be rotated to reveal its innovative craftsmanship.
