I have been wearing my new/pre-owned Aquis for about 11 days and have come to the conclusion that the Sellita SW200-1 movement just isn't very accurate. This is the second Aquis I have owned (the last two) that has been a real time gainer. The first Aquis I owned had the ETA 2824 movement in it and it was a great deal more accurate - +/-3 spd. The last two Aquis I have owned have gained at least 10 spd. I have no idea what kind of accuracy Sellita claims for these movements but I have had much better success with Seiko's 6R15 and 8L35 movements. I can understand better accuracy from the 8L35 movement because it is a hand made movement that is more expensive but the 6R15 movement is nothing special, certainly not any better than the Sellita SW200-1.
Not looking for answers just making an observation.
I know automatics vary in their accuracy. I get that. However, I just think that even an automatic movement, like the Sellita SW200-1, should be able to be accurate within 10 spd.
