Which way do the automatic watches wind?

Hey all,

This is a complete nerdy question, but I have a new SeaMaster 300 Professional and I’m curious about the automatic winding. It’s really a 2 part question but I’ve searched around and am not sure how to phrase it to get the answer I’m hoping someone knows.

Looking at the back of the watch, does the weighted rotor wind the watch in both directions and if not, which way is the winding direction?

Second, for those of you who have a lot more experience, once the watch is fully wound, if you’re at least somewhat active, will the automatic winding keep the watch wound indefinitely or will it still require manual winding and time setting occasionally?

Thanks in advance!

Modern Omega winds both ways. And yes, as long as you wear it every day, it will keep wound and will not require any additional winding from the crown.

Hi, and welcome to the forum!

You don't say which movement is in your watch, so for example let's say it's 8400.

Search Google for 'Omega 8400' to find details on that calibre. Here's one result that can be useful: https://watchbase.com/omega/caliber/8400

calibercorner.com can also be useful.

I hope this helps!

Thank you!

My apologies, I should have stated that. It is the 8800 coaxial.

As they said, both ways. Curiosity is important in collecting.

This was answered above, but yes the Cal. 8800 does have bi-directional winding—meaning the rotor will wind the movement in both directions.

As long as the watch is on your wrist, it should remain functional. You’ll notice some decrease in accuracy when the watch winds down, although Omega has controls against that.

Cal. 3330 only winds one way...based on the 7750...so it's still a mix.

Believe Felsa was the first manufacturer to produce a bi-directional self-winding movement in the cal.692 "Bidynator". I may be wrong but it is an excuse to post a photo of watch fitted with a Cal.692.

The first bi-directional automatic movement was produced in the 1700’s...

Good grief. Imagine engineering that in the 1700s. Sheesh.

In a wrist watch?

Pocket watch...

But only hula-hoop and jump-rope aficionados were able to keep it wound. 😁

My Tissot PRS 516 winds only one direction, but that rotor really spins a lot with only slight movement. My Omegas rotors don't seem to move as easily.
