Patek Philippe Nautilus 5712/1R-001 40mm Caliber 240 PS IRM C LU Movement Watch
A sophisticated 40mm luxury sports watch that combines the unmistakable Nautilus silhouette with an elegant brown gradient dial and a beautifully balanced display of mechanical complications. The dial transitions from warm brown toward deep black at the outer edge, creating a rich, changing appearance under different lighting conditions.
Horizontal embossed detailing adds depth and immediately recognizable Nautilus character, while polished baton hour markers and luminous rounded hands maintain excellent readability. The asymmetric dial layout brings together a 48-hour power-reserve indicator, moonphase display, pointer date, and independent small-seconds subdial without losing visual balance.
The rose-gold-tone case and integrated bracelet are constructed from copper-free tungsten alloy, finished with real-gold wrapping and Swiss PVD coating. With a slim stated case thickness of approximately 8.7mm, a bracelet thickness of around 2.5mm, and a substantial total weight of approximately 193.9g, the watch combines a refined profile with a reassuringly solid wrist presence. It is produced by UMI Factory and powered by a Caliber 240 PS IRM C LU automatic mechanical movement.

Materials
The case and integrated bracelet use copper-free tungsten alloy as their structural base, giving the watch its substantial approximately 193.9g wrist weight. The exterior is finished with stated real-gold wrapping together with Swiss PVD coating to create the warm rose-gold-tone appearance.
The rounded octagonal Nautilus-style bezel combines brushed and polished visual surfaces, while the integrated bracelet continues the same design language directly from the case. At approximately 2.5mm thick, the bracelet maintains a relatively refined profile despite the watch’s substantial overall weight.
The brown gradient dial is protected by sapphire crystal. Applied baton markers, luminous hands, horizontal embossing, and multiple recessed displays create depth without overwhelming the dial.
FAQ
1. Does the brown dial look the same in every lighting condition?
No. One of the most attractive features of this version is its brown-to-black gradient effect. The dial can appear warmer, darker, or more strongly contrasted depending on the viewing angle and surrounding light.
2. What does the power-reserve indicator show?
The display near 10–11 o’clock gives a visual indication of the movement’s remaining running energy on a 48-hour scale. The red section acts as a reminder when the available reserve is approaching its lower range.
3. How are the moonphase and date displayed?
Both functions are combined in the display near 7 o’clock. The moonphase window provides the visual moon-and-sky indication, while the surrounding pointer-date scale displays the calendar date.
4. Does the watch feel heavy despite its slim case?
Yes. Although the case is only approximately 8.7mm thick, the tungsten-alloy construction gives the watch a substantial stated weight of around 193.9g. This creates a solid wrist presence while preserving a relatively slim side profile.
