Azimuth’s SP-1 Crazy Rider: How it works

Azimuth’s SP-1 Crazy Rider features an innovative chain transmission system that is not only aesthetical but functional.

The chain transmission drives the hour and minute hands. The minute hand is found on the right and it is fixed onto the wheel. It completes one rotation every hour and the minutes are read off the conventional way.

The shorter hour hand is affixed onto the revolving chain and therefore travels with it, completing one round in 24 hours. It is what Azimuth terms a dial with a “true 24-hour scale”.

Time is therefore told by first taking note of the hour hand and the hour index it is pointing to, to read the hours, followed by a look at the minute hand to read the minutes in the conventional manner.

When worn on the left wrist with a long sleeve and half the case partially covered, one can still read the time easily from 7am to 5pm during office hours on the Azimuth SP-1 Crazy Rider’s 24-hour dial display. Photo: © TANG Portfolio / TimeWerke. Elfa / Timmy.

Of course, the rather unconventional time-telling takes some getting used to. For example, eleven o’clock (hour hand at 11 on the 24-hour scale, minute hand at 60 on the minute track reference) may appear to be 2 o’clock if based on the conventional way of reading time.

However, after having worn the Crazy Rider for a day or two, one will be able to familiarise oneself with its display.

If worn on the left wrist and a long-sleeved shirt with the Crazy Rider half-exposed, it may appear as a round watchcase. But this is not to be – the Crazy Rider has an unusual asymmetrical case that is designed to resemble a motorcycle engine. It is actually shaped like the infinity symbol and has a porthole-style bezel with exposed screws.

More importantly, With half the case partially covered, one can still read the time easily from 7am to 5pm during office hours.

After work and with sleeves rolled back, the Crazy Rider can be enjoyed in its full glory with time easily read off the dial. The hour and minute hands are applied with SuperLuminova for time-reading legibility in the dark.

From the rear, the movement of the Crazy Rider has been designed to look like an engine block. The automatic movement has been re-engineered for the Crazy Rider.

The base automatic movement is the highly robust ETA 2836-2. This can be seen if one can catch a good look at the movement which bears the ETA symbol and movement reference number.

Those who had attended the inaugural Watch Collector’s Masterclass in May 2016 conducted by HMF or Horloger Machines Fabrique, which is also a unit of Azimuth, ought to know as they were taught that this is one method identifying a watch movement.

The Crazy Rider’s chain drive system can be viewed as being inspired by either motorcycles or bicycles; it is up to each and every customer and what drives them towards such timepieces.
