Movement

The movement is a Ronda Caliber 4220.B analog quartz movement. It is Swiss made, has seven jewels and is gold plated.

Ronda weas formed in 1946 and has a good reputation for producing reliable quality quartz movements – there are many watch companies around the globe that use Ronda as their go-to quartz movement company. It manufactures movements in Switzerland and Hong Kong.

The 4220.B features a large date at the 6 o'clock, a small second dial to the 3 o'clock and the secondary timezone dial to the 9 o'clock. The movement features a quick set date at the first crown pull, with the second position adjusting the primary hands. A discrete custom pusher is at the 4 o'clock for setting the secondary timezone.

The standard battery life for the movement is four-and-a-half years but power consumption can be reduced by up to 70% when operating with a pulled out stem, useful for longer term storage. Being quartz you can expect the usual high level of accuracy that this style of movement provides, typically for the 4220.B this would be -15/+20 seconds per month.
