Got an Alpha watch with ST16 movements but problems ...

[watch_fanatic]

Yesterday got my Alpha watch with an ST16 movements and problems started to appear as soon as it started working.

• 1 When setting time, movement hacks as expected but as soon as I set it seconds hand jumps like 4 seconds
  
• 2 If I shake it, seconds hand just stops for a brief of time and after it starts working again and if I start looking at it I can see it starts gaining time. In about 2 hours it is like 7 seconds faster (so in a day over a minute)
  

I thought Seagull's ST16 was the best chinese 21 jewels movement around but after this experience ....

Does this all happens to all ST16 movements or did I get a really shitty lemon? Should I try to exchange it or does this happen to all ST16 movements?

Thanks for the assistance.
