My new Seiko 5 Sport loses about 5 seconds a day. Is this normal, can it be improved. How often do you guys adjust the time to set it right? (discuss.tchncs.de)

That's not bad at all. This level of watch should typically be +/- 15 seconds a day, so you're well within that.

Thanks. That’s good to know. I’ll have to remember to change the time every so often to make it accurate.

To my knowledge, the only automatic movement that is going to be notably better in terms of accuracy is Seiko’s Spring Drive, which will get you to +/-15s per month. It’s actually a fascinating bit of mechanical and electrical engineering, and one of the few real innovations that have occurred in mechanical watchmaking in quite a long time.

In terms of adjustment: I usually set my watch a tad fast (i.e. round up to the nearest minute) on my seiko, because it doesn’t have hacking seconds and is kinda fiddly to get it to sync super precisely, and then just tweak it when I notice the time getting out of whack with what my phone or computer says.
