Royal Oak 56175 Championship

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.

It is quartz, so it will hold time far more closely than any mechanical watch here, and asks for a battery every few years rather than a service.

56175TT.O.0789TT.01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a grey dial with a yellow gold, tantalum, stainless steel case. It was a limited edition. Introduced in 1991.

Quartz movement with hours, minutes and date. Battery : No 315 Voltage : 1.55 V
