Patek Philippe
Nautilus Moonphase
The Nautilus Moonphase — the most complicated reference in the modern steel Nautilus line. Power reserve, pointer date, sub-second + moonphase, micro-rotor calibre.
On this piece
The 5712/1A is the multi-complication Nautilus — power reserve at 10, sub-second and moonphase combined at 6, pointer date at 7, hours and minutes centrally. The calibre 240 PS IRM C LU is one of Patek's most technically interesting modern movements: a self-winding micro-rotor architecture (the 22k gold rotor sits inset into the movement rather than on top, allowing the 8.52mm overall case thickness) running at 3Hz with a 48-hour reserve. The case-back is sapphire. Patek discontinued the 5712/1A in steel in 2024.
