I just got my Dynamic III serviced at Womble watch in Marietta, GA. It is still dead on accurate after a week. Any bets on how long it can last? Is this normal for a just serviced watch?

You are sure you set it within a second? No, it's not normal, it is above average accuracy. You expect these to be within 5 seconds a day or so when a good watchmaker services them.

I don't know how long it should last. Probably is different for every watch. It will be less accurate 6 years from now, that's for sure.

It gained a second a couple of days ago, but now we are back to dead on. I am going to keep wearing it to see when it falls off. It was losing 90 seconds a day when I took it in.

My dynamic lll lost a second a day on my wrist and gained one and half at night for 20 years. It came a back from a recent service not doing that well. Previous service trips always returned to the same excellent time keeping. I’ll see if it settles down but maybe it’s showing its age. I know I am!

Sounds less accurate than dead on, if it gains seconds some days, loses others. But that's great that it generally keeps good time.

I had my Mk40 chronograph serviced over a year ago when I purchased it pre-owned. After an independent service, my timegrapher showed essentially a flat line. It still does. But wearing it in the real world, a lot of factors are going to influence the accuracy during the course of a day.

As stated above, this is very dependant on how the watch is used but averaging out to dead on is pretty great and a little lucky in my view. As long as it's meeting COSC requirements (Was the Dynamic a chronometer?) I'd be happy.

For an anecdotal data point, my 2504.52 with a Caliber 2403 came back from a factory service a couple years ago averaging about +4 s/d when worn. It's fast in every position so if I were to be nitpicky I think it could have been regulated a little slower, but it meets COSC so I'm happy.

Looks like I am a second fast this morning. No Dynamic was not a Chronometer. it has an ETA 2892 movement. Really happy to have it working great after being super off.
