In this picture, you can see them side by side with quartz on the left and mechanical on right. Now here's the overall comparison between the two.

The Seiko VK movement is quartz, so it is extremely accurate and should last longer than the A7750 movement in theory.This is considered risky as they typically do not use jewels with the gears that take that movement to the 3 o'clock position and so this part may fail one day and possibly take out the whole watch. This TAG model however has the seconds movement on the oposite side at 3 o'clock. The Asian 7750 movement appears to be a decent substitute for the real thing, but the seconds gear is always at the 9 o'clock postition on the movement.Full disclosure, I do greatly prefer mechanical movements over quartz.įor those new like I was, here's a few things you should know before deciding: I decided to buy both and do a comparison for everyone. As this was my first rep, I wasn't sure if I should stick to a true asian mechanical movement or give the new Seiko VK quartz a try.

I admire the Calibre 17 model with its excellent symmetry and beautiful design. So my very first rep watch purchase was going to be a TAG.
