The Master Ultra Thin Power Reserve in pink gold is distinguished by the purity of its lines, the architecture of its dial and the readability of its functions. The elongated hour markers and Dauphine hands with a polished and satin finish stand out against the sunray background of its midnight-blue dial, forming a magnificent contrast with the pink gold of the case. Beneath the hands, at the heart of the blue dial whose nuance increases in intensity from the centre towards the bezel, the opaline counters form a perfectly harmonious whole: power reserve on the left with zero level indication in red, date hand on the right and small seconds at 6 o‘clock. Created through a complex and meticulous manufacturing process, this intense, luminous blue is a perfect match for the navy-blue alligator leather strap. The transparent sapphire crystal case-back offers an unobstructed view of the almost 300 components of the Calibre 938, which promises 70 hours of power reserve.

MASTER ULTRA THIN POWER RESERVE

DESIGN

A DISTINCTIVE DRESS WATCH

The Master Ultra Thin Power Reserve embodies the ultimate combination of technical understatement and sleek aesthetics. Its design and slimness ensure that it is a subtle and elegant watch on your wrist.

A SOPHISTICATED BALANCE

Blending symmetry and balance, large sub-dials make the date, power reserve and small seconds displays more legible. The elegant case and elongated lugs are complemented by the refine design of the dial: elongated hour markers, Dauphine hands, golden dots minutes track, and a sunray-brushed finish.

FUNCTIONS

A GLIMPSE OF THE POWER RESERVE

The Master Ultra Thin Power Reserve indicates, in a glimpse, all useful watchmaking functions: a power reserve gauge, allowing the constant review of the functioning of the watch, a small seconds counter and a practical and elegant date display.

HERITAGE

A SIGNATURE COMPLICATION

The Power Reserve is a signature complication of the Manufacture, pioneered in 1948 with the introduction of Calibre 481. The Powermatic, recognised by its distinctive red-and-white indicator, was the world’s first self-winding timepiece with a power reserve gauge. The Master Ultra Thin Power Reserve is equally recognisable, distinguished by its design.

CALIBRE

HIGH-PERFORMING HEART

Entirely made within the Manufacture, the latest generation of Calibre 938 presents an increased power reserve of 70 hours, lasting beyond the weekend, without adding to the size of the calibre. It offers a high reliability thanks to silicon escapement wheel and pallets, making the energy transmission smoother by reducing friction of the moving parts.
