I yielded to temptation about a month ago and finally purchased a Seiko Black Monster. I love this watch! I replaced the stock rubber strap on the watch with a Seiko Z22 strap which only required a little bit of trimming. I just think the wider strap compliments the watch better. Anyway, it’s freakishly accurate. Since I’ve started wearing the watch, it has drifted within 1 second. The thing is more dead-on than any quartz watch I own (and certainly far more accurate than my SKX-173 which gains around 10 seconds a day when fully wound…and that’s not shabby from what I understand). Did I just manage to hit the jackpot with this particular watch or is performance like this routine? Should I expect a larger degree of drift as the watch is broken in? As an aside, I very rarely take the thing off…I don’t wear it in the shower, but other than that, I like having it on my wrist. Maybe that’s helping out?
