AuthenticSellita automatic chronograph watch movement SW510-1.
Sellita is a Swiss movement manufacturer and for the most part copies ETA movements. It was the main supplier for ETA, and it has all the machinery capable of reproducing the very same parts as in the original ETA branded movements. Due to the ETA attempts to regulate the provisioning of their movements, many watch manufacturers are basing their calibers on Sellita as an alternate high quality Swiss movement manufacturer.
The caliber SW510-1 has a traditional chronograph layout (3–6–9), that is, a 30 minutes counter at 3 o’clock, 12 hours counter at 6 o’clock and small second counter at 9 o’clock. Quick setting of the date is activated via the crown.
