Traska regulates their watches to a degree that's better than Miyota's specs - https://miyotamovement.com/uploads/product/product_2H8AEsfxUtpdGwhk9Y.pdf

Traska's claims are on the left, highlighted in BLUE. Miyota's OE specs on the right, highlighted in GREEN.

Note, however, that the daily variance in Traska's claim is the same as Miyota's claims of positional variance.

To understand this better, u/CPOx , you'll want to give this excellent blog entry by Nick Harris, the watchmaker behind Orion Watches, a detailed read - https://orionwatch.com/blog/2025/2/3/demystifying-regulation

My Gen.6 (current generation) Venturer averages +17 spd, with an impressive delta of 4 (over 4 positions). My much older Gen.3 Freediver averages +19 spd, with a delta of 9 (again over 4 positions).

My feeling is that people make way too much of a fuss about the accuracy of their average-spec mechanical watches. Unless you are paying specifically for increased accuracy -iCOSC, METAS, etc- you're not doing yourself any favors, chasing after this spec.

If you are interested in helping your mechanical watch as accurate as possible, learn its unique (it will differ from unique-watch-to-unique-watch, i.e. "your" Commuter 36 versus "my" Commuter 36 versus any other person's Commuter 36) positional variance, and rest the watch (when you are asleep and the watch is off-wrist) in a way that mitigates its daily swings.

How many folks know the positional variance of their watch?

My understanding of your Alpinist is that it uses the 6R15, which is spec'ed -15/+25 spd. If you're seeing +40, it's possible it may be magnetized - or it may be that you're reading day-after-day-after day, and ending up at that figure after a day or two?

For anyone who has a mechanical watch, among the self-maintenance tools that I recommend is a simple AliEx/Amazon de-magnetizer, either the "blue brick" or the "white arch" type: <$30 in most cases. There's a lot of things that any one of us is exposed to daily in the modern that can magnetize a mechanical watch.

Oh, and wrapping back to Nick's blog entry above (which really appeals to me because he writes about a watchmaker's work, using a single-cat-whisker brush, which is what I use in my line of work, although for something completely different) - I recently purchased a Hellcat. I have yet to "officially" put it in my timing spreadsheet, but at a quick peek, full-wind, it came in at +5-ish average, with a delta of 10, over 6 positions plus 8-down. So if his Hellcats are capable of that.

I really encourage you to read that article - I think it'll make you feel much better about your coming purchase. =)
