The Orient caliber F4902 is a self-winding automatic movement with 21 jewels. Orient makes their movements in-house in Japan. This is a non-hacking and non-handwinding movement. You may have seen other sites list this movement incorrectly as caliber F49-02 or F.4902, but Orient officially writes the caliber number as F4902.

F4902 VS 46943:

The Orient caliber F4902 is said to be an upgrade to the caliber 46943. The main difference is that the older 46943 has a pusher on the side (2:00) to change the calendar (day of the week), while the newer F4902 calendar can be corrected via the crown.

Power Reserve:

The Orient caliber F4902 has a power reserve of 40 or more hours.

Setting the date:

Avoid setting the date on your F4902 watch within the hours of 8:00pm to 4:00am.

The F4902 Caliber can be found in a large number of newer Orient models, from diver watches to other kinds, like casual-looking ones, fliegers and so on. The reference for those models always start with F49, followed by the material indicating code (SS for Stainless Steel, TT for Titanium, SC for steel case and leather strap) and a number. I own two watches powered by the F4902: The limited edition diver F49TT001 and the flieger-looking F49SC012, wich has an glass back, allowing you to see the movemente. Classy.
