I just wanted to let you all know that my fathers Delvina Geneve watch has finally decided to keep good time.
I was on the verge of just not wearing it anymore and buying a quartz-watch again, but I'm very happy I didn't.
After Ray MacDonald gave me the tip to try different positions, I discovered that it didn't gain or lose anything when kept crown up (the watch has a tendecy to gain a lot the first three hours after I've wound it).
So, I just wind it when I go to sleep, keep it crown up during the night and it's perfect on time when I wake up.
I did that for about a week, and then I discovered that it actually ran quite accurately. It gained around 6 seconds a day. So, about four weeks ago I've let my watchmaker re-regulate it for the last time, and it has been gaining 1/1.5 seconds a day!
According to JimH in the same topic the ST974 was just "an average quality movement which might have have been accurate to -20+20 seconds per day when it was new.".
So either this watch hasn't got the ST974, or it isn't so bad after all. Either way, I'm very very happy.
This Delvina is still my only good watch, and I'm wearing it everyday.
And I've also been thinking about ordering an Alpha-watch. They're made in Hong Kong, and their mechanical watches. Their very cheap. Almost too cheap. But my brother has ordered one of them, and it has been quite a good watch, keeping time to within 15 seconds a day. And whenever they need a service, you can just throw them away and buy a new one.
So I'm going to order this watch to keep as a beater. I just hope mine will keep good time too .
