    It’s cool to see the new watches having over 60 hours power reserve. Ive been a watch guy many years but just starting to get into bigger things. A couple old rado I have are a solid 24 and it was made in 1970. I have a Hamilton that edges forty. Anyone have anything over 60 hrs

    I have a 16-size, 21-jewel Illinois Bunn Special 60-hour model. It has run for 62 hours on a winding.

    I’ve never really understood the race to squeeze a greater power reserve out of a movement. As long as it makes it through the night, I’m good. If I take a watch off and don’t plan on wearing it for two or more days, I want it to power-down. There is a good chance I won’t wear it for a week or more.

    My Blancpain Villeret has a 72h reserve, but when I’ve left it unwound it lasts at least 2-4 longer than that

    I had a Leman with a 100 hour reserve - it was very accurate as well.

    Do quartz power reserves count? I have a solar G-Shock Frogman, it's been running since I got it last year :)

    I really like the Leman models, but it looks like they might have discontinued them (no longer on their web site). No complaints about the accuracy of my BP either - it's doing great and overall I'm very happy with the quality of the watch.

    I get you, to me it’s the engineering of the movement that goes into having that much on reserve. When I was reading the new omega catolouge and see 40hrs is standard 60-80 reachable and now someone on here with a weeks worth of reserve speaks on the workmanship of the watch. I find it a fascinating aspect of automatic watches. I should say I have this vintage wind up Vostok and the thing runs two and a half days on one wind up. I wasn’t thinking mechanical but yes some of them are quite impressive

    That is crazy I could look it up myself but do you know if that about the Max. I’ve read some articles about IWC great history in that company

    Ha beautiful thanks. I remember the first time I went to China i was a bit ignorant and thought with the exchange rate I’d find a good deal on a nice watch. I checked out a few of the authorized dealers in Beijing and Shanghai and found these items are priced about the same as in the US. As soon as I walked out the door I had a choice of any high end watch ever made for 11 rmb but no such luck.

    the 7 day (which normally lasts 8 days) is, I think, their longest reserve watch.
