I had a seiko 5 and found it noisy and it just felt a bit rattly or loose, it was also a terrible time keeper.
Hmmmm, there’s a problem with that, then. Neither of my Seiko’s are at all audible, in any circumstances, even utter silence, and the 5 is no worse than any digital watch like my Casio. I haven’t worn it for extended periods since I got my SPORK, and that is very accurate now I’ve tweaked it, but I don’t think the 5 is more than a minute or so a month out.
My 70’s Yema, which is pure mechanical, is fairly loud when it ticks, I can hear it a metre away late at night, but otherwise it’s a lovely movement, now it’s been serviced. Same movement as Raymond Weil and Breightling used back then, apparently.
