A Sekonda Classique from the same junk pile lot as the Seiko 7N32 above.
Not quite as attractive, arguably, but not bad for 1/7th of the £3.20 the whole lot cost (or to put it in context, less than the cost of a Mars bar).
Other than very slight pitting on the clasp, and of course a flat battery, there was nothing wrong with it.
A quick polish and a fresh button cell and it joins the club.
That's the ratchet wheel. You will need to remove the screw, block the wheel with a piece of pegwood or toothpick so you can unscrew it. 9 times out of 10 they are regular right hand thread, but as watchweasol said it could be left hand. Try gently both directions, increasing your force till it goes. They upside of doing it like that is if the thread is a little stuck, often tightening it slightly will help it loosen. Seems odd but it works.
