Interesting it's the same rate so far for the CW watches and I agree that level of "domestic" charge is probably as rigorous as any.

Interesting and useful topic. I tend to rotate on a weekly/fortnightly basis so my other automatics sit on the winder.

I also do lots of car stuff so wear an old well-worn Seiko Kinetic for this.

Experiment number 3:
Rolex Milgauss
In-house 3131 COSC PR 48 hours

It stopped at 6:42am this morning. 43.5 hours of power reserve for 3 hours of leisurely wear. Whilst I had expected it to last longer per hour than the Sellita’s for the same pattern of wear, I didn’t think it would keep going for so long.

14.5 hours of power reserve generated from each hour of wear.
