Seiko movement accuracy hack.
Seiko watches are pretty awesome, but those of us with Seiko automatic watches tend to suffer from inaccurate time-keeping, because the movements are not factory-adjusted before being sent to market. The following hack is well documented, but I wanted to share it here for those Seiko owners that might not yet know, and are bothered by this aspect of their Seiko purchase.
Steps:
Use a timegrapher to see what spd you are gaining/losing at various positions. I've used a timegrapher app for this purpose, because the data doesn't have to be exact, you just need a consistent general idea of the data at each position.
Record data for a week of regular wear to see what your daily gain or loss in spd is - an average will do.
Find the position that your watch should be in to offset the average gain or loss from your timegrapher data.
Store your watch in that position when not wearing it, and this could offset your daily spd change to an acceptable amount.
For my SPB121 in the title picture I found that regular daily wear left me with +4 spd, but placing the Alpinist dial up at ~20 degrees rising towards the 12-marker my spd is consistently +3. To put this value in perspective, if I stored it at 0 degrees dial up, my spd rises to +12. That bothered me hence I used the hack.
Note: Your mileage with this technique will vary.
Of course you could just pay to have it adjusted with your local watchmaker, but if the hack works satisfactorily there might be something of value here.

It's a great suggestion. I would add that the 6r35 can change with time so you may have to reassess it every few months. For the first nine months I had my SPB210, it was a steady +7s/d if I stored it crown up. Then after a couple of bouts of being magnetized (and demagnetizing it), I found that it was now at - 12s/d. But I've been storing it crown down and it's only about - 5s/d now.

Thanks, this is a good add.
