Self winding reps?

[ag816]

Total Newbie question -

I've been looking at a few of the watches at some of the trusted dealers - Are the A7750 and other movements self winding if worn throughout the day? I purchased on a few years ago (not sure of the movement), and I need to wind it every day or two otherwise it stops. I am wondering if this is a common thing with the reps or are other types of movements self winding if worn normally throughout the day.

Thanks in advance!

The A7750 movement is called an automatic movement. What that means is there is a weighted rotor inside the watch that swings around from centrifugal force, and that swinging winds the watch. This is common to the majority of mechanical watches (i.e. not battery powered watches), the other method for winding is via the crown on non-automatic watches. It is normal if these watches are not warn for a couple of days to stop working, until they are "wound" again - either by wearing the watch or winding the crown. The genuine watches operate in the same exact manner.

Watches can be battery quartz, hand-wound or "Automatic" (self winding) ...

This is different for every watch you buy. Just read what the vendor says in his description.

If you work at a desk and do not move around very much during the day, even Automatic watches can run out of power in a day! No arms swinging = no power.
