Calatrava 3718 150th Anniversary Japanese Market Ivory

In Context

At 33 mm it is small by current standards, in the range most wristwatches occupied before cases began growing through the 1990s. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. Rated to 30 m, it is protected against rain and splashes and nothing beyond that.

The movement is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 44 hours of reserve carries it overnight, but not through a weekend in a drawer. At 28,800 vph the seconds hand advances 8 times a second.

3718A Ivory is one of 2 executions of the 3718A base reference. Underneath they are the same watch; what separates this one is a ivory dial and a stainless steel case. It was a limited edition. Introduced in 1989.

The 215 PS is Patek Philippe's small hand-wound movement with a small seconds, made since the 1970s and the caliber of the classic Calatrava. It powers 23 watches in this library. It is 21.9 mm across and 2.55 mm high, with 18 jewels, a Gyromax balance beating at 28,800 vph and a 44-hour reserve, and it carries the Patek Philippe Seal. Its thinness is what keeps a Calatrava under 8 mm, and its size lets it serve the shaped cases of the Gondolo as well as the round ones. In the library it powers 17 [Calatrava](/brands/patek-philippe/calatrava) references, the 5119, 5196 and 7120 and the 6127, and 6 [Gondolo](/brands/patek-philippe/gondolo) 7041 references. Cases run from 30 mm to 38 mm. 4 are limited editions. The [240](/calibers/patek-philippe-240) is the ultra-thin automatic of the Calatrava, and the [30-255 PS](/calibers/patek-philippe-30-255-ps) of 2021 the larger hand-wound movement that succeeded the 215 in the 6119.

22 other watches in the library run the Patek Philippe 215 PS.
