Portuguese Hand-wound Pure Classic Stainless Steel / Silver

In Context

At 42 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse.

The movement is hand-wound, so winding it becomes part of the day rather than something the watch does for you. Its 36-hour reserve wants wearing most days; leave it off and it stops. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

IW5703-03 is one of 2 executions of the IW5703 base reference. Underneath they are the same watch; what separates this one is a stainless steel case. It was a limited edition.

The 62060 calibre has a bridge and plate decorated with Geneva stripes and cicular graining. at just 2.5 milimetres in height, this was a movement that was seemingly predestined to grace the slim and elegant IWC hand wound pure classic.

1 other watch in the library runs the IWC 62060.
