Watch Accuracy Shootout
And here we go! I'm bored, so measuring accuracy of my 3 favourite mechanical watches. The results may surprise you :-)
First up... My Sinn 104. Lovely watch:
Running at just over -2 s/d, on the timegrapher it is a very solid watch. It was serviced last year and runs very well. But under real conditions it runs around -4 to -6 seconds per day.
Next up.... My Tudor BB58:
Only just making COSC at -4 s/d. In real world, its running a bit slower than that, at around -5 s/d. I've had this for 4 years, and it hasn't been serviced. That narrow line and tiny beat error tells a good story in comparison with the others.
Finally - my Hamilton Pilot Pioneer Khaki Mechanical:
Running at +2 seconds per day, this is an absolute peach of a watch. In real world, it runs around +3 s/d. I've had this for 6 years and it shows no sign of slowing yet. There's a few hiccups in the movement, but I haven't wound it for a few days, so I'll give it some leeway. reckon it'll be OK for a while, but might need a service before long.
So there you have it. 3 watches, 3 different price ranges, two "in-house" movements, one Sellita. The Tudor is the least accurate on a timegrapher, but is more positionally stable than the Sinn, perhaps due to the balance bridge. The Hamilton is the most accurate (and the cheapest).... Go figure!
I got my first mechanical watch in 1976 as a boy. I broke it within a year (over wound it). Then after many Casio years, I rediscovered mechanical watches. Still have a couple of quartz watches, thoug...
I have 3 watches with an 80 hour swatch group movement (Rado, Hamilton,Tissot) - all of them keep better time than my Breitling Superocean, which cost at last 4 times as much as the others (and is currently with Breitling for repair under warranty)……
I have a $160 SanMartian that’s 1 second slow per day
My khaki pilot pioneer also runs about 2 secs a day. Had no idea that watch has been out for 6 years, I could've sworn it came out in 2021.
Last week I built a watch using Chinese ST3600 that I bought on eBay. As you can see, it is also runs pretty good.
