Introducing: Patek Philippe’s 50th Anniversary Nautilus Collection, Two Large Size and One Midsize Limited Edition Model (And A Desk Watch!)

As hoped, Patek Philippe could not stand to let the 50th anniversary of its iconic Nautilus model go by without at least some celebration. Removing the center seconds (à la the original 3700) and eschewing a date, the new 41 mm by 6.9 mm ref. 5810/1G-001 and 58101G-001 are the new “Jumbo” Nautilus, of sorts, but we should start with something bigger—or rather, smaller.

The new ref. 5610/1P-001 is, in a way, a celebration of the old ref. 3800 midsize models, with a 38mm by 6.9mm platinum case, with a diamond set into the 9 o’clock ear. With no date, no center seconds, but the full platinum bracelet experience, the watch is something we haven’t seen from Patek in quite some time, given its size and dial layout. It keeps the sunburst decoration under a blue PVD coating, Nautilus horizontal-relief embossing, and white-gold hour markers with Super-LumiNova.
