Jump date workaround?

I have a 2016 PO coming in to celebrate a major milestone professionally. I got a good deal from an awesome guy.

Doing some reading and I’m just curious if there’s a workaround for making sure the 8500 jump hour issue doesn’t creep up. Only changing the date via the furthest out position and just looping around 24 hours? It was serviced in 2020.

Assuming it’s one of those things that is “worse” on forums than in real life.

Thanks! Can’t wait to show off the new PO.

I have an AT with the 8500 movement and this is a concern for me (a minor one). My suggestions:

1) Keeping in mind you can go backwards, choose the shortest route to the current date.

2) If you are constantly putting the watch away and having to reset the date every time you pick it up, you can just leave the date wrong and only set the time.

3) Put it on watchwinder so the date is always correct. This will add wear and tear to the entire movement so this may not be the best choice.

4) Just do whatever you want and if the hour wheel breaks get it fixed.


If I think I'm going wear the watch for several days I do #1. If I think I'm only going to wear it for a day or two I do #2.

Since it was serviced in 2020, the hour wheel should have been replaced because this is the item that wears and causes the problem. So, wear it and enjoy it. If the issue arises in the future, just have it serviced then.

It’s going to be my main piece so I imagine I’ll set it once and probably won’t ever go 60 hours between taking it off and putting it back on. Can the hour wheel be replaced or does it require a full service?

OSC would require a full service. An independent Omega certified watchmaker would probably do just the hour wheel if that's what you wanted. They are a lot more flexible.

If you will not constantly be changing the date manually I wouldn't worry about it. I'm concerned because the jump hour watch I have I only wear sporadically so it would be a lot more date setting in the course of a year.

Hard to find a certified watchmaker these days. Even Nesbits charges more than OSC

Not so sure about that - most good independent watchmakers aren’t willing to replace a single part without doing their own service of the movement that they can warranty. They do it, something else goes wrong shortly after, guess who’ll be blamed?

It’s the same reason most independent mechanics refuse to replace parts that a customer provides.

It depends on the watchmaker. I know mine would do it. But then I've worked with him for years and he knows I'm not going to blame him for a choice I made.

Sounds like you found a good one! I still can’t find anybody local to me.

Exactly. A watchmaker is highly unlikely change a part without a full service for someone just off the street. It’s not worth the hassle unless there is a prior relationship.
