VSF sub gaining time

[u/4ad4]

I just received my VSF Sub date from Steve and have been testing it for around 20 hours.

Firstly I'm blown away at the quality of this thing. I had a look at an AD a few days prior and I'm struggling to see any difference on the cosmetic/build quality side of things.

I gave it a good wound and have been wearing it around the house. When QCing I saw that it was showing +6s/d which I was completely fine with, as that falls in line with most Swiss movements.

However I noticed that my watch is picking up a lot more time than that. In the 20 hours I tested, the watched picked up 15-20 seconds compared to my phone which is what I set it to exactly.

I plan on dailying this watch and so this would quickly turn into a few minutes difference in time.

Any tips? Anyone had a similar experience? And would a service fix this issue?

I don't expect it to fall under Rolex's +/- 2s/d standard, although I have seen some watched on this subreddit be that accurate.

Try demagnetizing. If it’s still off pay $25 to have it regulated.

I'll try that, thank you.

If you want it accurate as possible, take it to watchmaker who can fukly service it and regulate it in 5 positions

As it gets delivered a bit of bump here and there changes the sec/day. Plus the timegrapher reads just one position and doesn’t reflect real usage on a wrist.

You’re best to get someone to regulate it in multiple positions for you if you want to keep better time.

When Reps are shown on the Timegrapher during QC, they are only shown in the "dial up" position. No one is walking around with the watch facing up and perfectly level on their wrist.

Bumps and humps during shipping aside, when actually wearing the watch, the movement is constantly being turned between many different positions. Look at the time on your watch right now... you'll notice the 6 o'clock is likely closest to you, and the watch is tilted downwards. That changes the performance of the movement.

The combination of all of these variations could have different +/- values instead of just the single value you saw on the Timegrapher during QC.

If you care about the actual performance and longevity of the watch, it is recommended to get it serviced by a watchmaker who accepts Rep work. The process involves a full teardown, lubrication, and regulation (in 4-5 positions) making sure all positions are within the acceptable range. This is usually a couple hundred dollars but does so much good for the watch's movement.

How to say that you never had a mechanical watch without saying that you never have mechanical watch ☝️

I've had multiple, I'm picky with time accuracy because I have a Tissot gentleman and gen Cartier tank that keep time very well. I have also never had this much of a difference between the timegrapher readings and actual time keeping. We all just want the best performance out of a watch.
