DISCLAIMER: Put this in the "Totin" thread but decided to share here ...
... and a 2015 NORTHWOODS INDIAN RIVER JACK ...
Not really into time since retirement 16yrs ago but spent a little time tonight with an old hobby of mine.
I've always preferred automatic watches with analog faces and I used to try and get them into the best possible adjustment.
I'm happy with the accuracy and precision of this watch now. +2 sec/day 0.1ms beat error.
While the movement is not certified as such, it is quite well within COSC Chronometer compliance.
It is more accurate and precise than about 99% (i'm scientific like that) of the automatic watches out there.
Could it get it even more accurate and precise? ... maybe, but it's good enough for now.
Is it as accurate as a quartz watch, the clock on your cell phone, or computer? ... no sir. I have a radio controlled Casio Lineage for that when necessary.
This little watch hobby of adjustment is just as relaxing and rewarding as sharpening a knife ... to me anyway.
I many other watches that I just as seldom wear any more. This Watch ...
Tisell Pilot Watch 40mm, Type A with Diamond Crown
Sapphire Crystal with AR Coating on front and Mineral Crystal on back
Super Luminova BGW9
Auto Winding MIYOTA caliber 90S5, 24 Jewel movement
On a Hirsch Natural Rubber strap
While I used a GREAT phone app to check and adjust the watch this evening, I do have an old Mumford Micro Systems Clock and Watch Timer that I used to use.
... and NO, I do not work on other peoples watches. Even after many years (decades), I'm just a hack and not watch repair trained.
