We deeply focused on watch modification and movement tuning. As such, absolute accuracy is always on our important checklist. We ensure the quality of every parts by using strict control testing standards before assembling the watches.
All our watches have to pass all of the above procedures before delivery.
We make sure that the accuracy of our watches are highly maintained in -20~+20 seconds/day. We tested the watches in more positions than the normal quality checkups do - we tested the watches in 5 positions while the others tested in 3 positions only.
As we have modified the movement, we need to ensure the watches are adequate in every situations. We then tested the sample watches on wrist for more than 9 months before we started our kickstarter campaign.
The stableness of BEHRENS ORIGINAL watches are highly guaranteed.
