Technical & Craftsmanship

We pride ourselves on continually investing in development, innovation and technology. Our watch winders are made to gruelling standards by our expert craftsman.

Why use a watch winder?

An automatic watch has a mechanism that requires regular motion to keep the inner spring constantly charged. This motion is usually provided as it is worn. Once removed from the wrist the stored energy will only run for 24-72 hours, depending upon the model, then the watch will need to be manually rewound and reset.

Many automatic watches have additional features, or “complications” - date/lunar phase/world time etc. so the task of rewinding and recalibrating a watch if it runs down is best avoided.

Furthermore, watches of such calibre are precision instruments and like all thoroughbreds they actually benefit from exercise - if left unwound for long periods, internal lubrication can be lost from critical areas which will eventually lead to excessive wear on components and subsequent lack of accuracy.

Perpetua Watch Winders have features designed to mimic the action of a watch being worn. The watch is held at a precise angle while being rotated and the winder can be set to run intermittently so that the watch is not permanently fully wound.

Luxury soft feel interior

The build quality of these wooden boxes can only be described as luxurious with the outer surfaces being finished with hand applied lacquer and the interiors being lined with a soft feel velvet fabric which not only looks good but adds to the protective environment for your prestigious watches.

Choice of settings

Two modes of operation are provided: a fast winding mode, when the drum rotates continuously, and a timed mode which rotates the drum intermittently clock-wise and anticlockwise.

Electricity and Mechanical

The control and drive systems operate on a safe low voltage direct current (below 6VDC). Most Roroos winder models can use both batteries or a plugged in DC adaptor interchangeably. An integrated circuit controls the running of the winder and it is programmed to give an effective winding action and yet controls the consumption of electric power to a very low level.

The drive system is housed inside a zinc alloy die cast gear box. Power is transmitted from a DC motor at one end to an output shaft at the other end smoothly and silently.

The electrical and drive systems are designed with minimum ease of maintenance in mind.

We strongly recommend the use of the power adaptor but the chart below gives an indication of the life expectancy when good quality alkaline batteries are used.
