Object description

Case and Dial

The watch is housed in a two-body, rectangular curved case constructed from 18K pink gold. The case features a combination of polished and brushed surfaces, with straight lugs and screwed pink gold bars for the strap attachment. A sapphire crystal covers the dial, and the case back is transparent, secured by eight screws, allowing for visibility of the movement.

The dial is crafted from white ceramic and is dominated by a monochrome erotic scene executed in a style reminiscent of Picasso. Roman numerals are placed radially around the dial, and time is indicated by pink gold pear and epee hands, contributing to the distinct aesthetic of the MuchMore collection.

Movement and Escapement

It is engineered with 25 jewels and a straight-line lever escapement. The timepiece is precision-adjusted to five positions and includes a shock-absorber system for durability.

Regulation of the movement is managed via a micrometer regulator, and it is fitted with a self-compensating flat balance-spring. The quality of the construction is confirmed by the presence of the Geneva Quality Mark, which is stamped onto the movement. The movement, dial, and case are all signed by the maker.
