ROLEX Oysterquartz Datejust ref.17000 / Black Dial

Rolex means the Oyster case and the Perpetual, but this model is something of a maverick: Rolex's answer to the quartz crisis.

A quartz model popular for its distinctive case design, and one many people are looking for.

In recent years it has been well regarded abroad too, and supply feels likely to tighten.

A squared tonneau case and a three-link hard-plate bracelet give it an appealing form quite unlike an ordinary Oyster.

Few were made in the first place, and the black dial is scarcer still, so it is highly recommended as a collector's item.

It has a quick calendar and a hacking function.

Serviced, refinished and given an ultra-thin protective coating by Hakkindo, a former authorised Rolex dealer — the highest level of quality, so that it feels like new. The coating's resistance to scratching and impact has been confirmed by third-party testing.
