A watch without a dial? The Masterpiece Square Wheel does not follow convention. It dispenses with a normal dial, instead revealing the move- ment bridge, effectively the chassis of the movement within.

The stainless steel case, measuring 43mm in diameter, provides the opti- mum size for the depiction of time, ensuring ease of readability.

The “Classic” features a black canvas on which to express time. Dia- mond-polished and faceted, luminescent Hours and Minute hands stylishly convey the moment. An alluring three-dimensional quality is accorded to the display. The applied indexes and power reserve indicator scale sit proud of the movement bridge interfacing with available light and enhan- cing legibility.

The “Vintage” employs a white lacquered dial imbued with a successful fusion of retro-inspired elements. The hands share the same appearance as the “Classic” model, but in this instance, interface with black printed indexes and power reserve indicator scale.

Both models feature two overlapping circular recessed areas, providing demarcation for the clover-shaped and square wheels. Moreover, the wheels are circular brushed to highlight their form and draw the eyes to their mesmerising motion.
