@Laneside Thanks! Milljonär is still in my collection and in regular use. Watch keeps ok time, losing about 20s a day. I've had the movement serviced by a local watchmaker. Unitas 6325 caliber can be regulated to run pretty accurately.
At the current rate of exchange, 0.53 pounds will buy a Canadian dollar. Your watch would cost close to about $362.00 Cdn. Glad you like it! Probably worth all of that if it is solid karat gold.
We found a box of watches in my girlfriends grandmother's attic. Couple were worth polishing up and adding a strap to. The style was apparently gold on flexible bracelet in those days.
Oh, I have (and had) lots of cheap beauties. Here are a few for starters. These four cost me probably 50€ in total. Likely less. Well a bit more perhaps if you count changed crystals, straps and such. I hunt a lot at flea markets, antique stores, buy and sell sites etc.
