Don't Change the Date Between 2200 and 0200?

[No SUBctitute]

I was at the AD several days ago and looking at a Tag and a GMT. While I was looking at the Tag and we were talking about the different crown positions, he told me that I should not change the date between 2200 and 0200 because that's the point when the date wheel started to engage and I could permanently damage it. I asked is that was true with Rolex, too. He emphatically said, yes. So, I'm bringing it to the pros: is this true, should I not adjust the date when the time is between 2200 and 0200?

I was told by PP AD too.

Not true, the AD is a

PP might have troubles due to their fragile slow changng movements, yet no worries with a Rolex.

This is true for many movements and I have seen the damage it can do. But nowadays most (if not all) movements like Rolex produces cannot be damaged that way.

I've heard this on some chronos, an AP AD in Selfridges was freaking out when I tried to adjust the ROC. Not on any Rolex.

I've heard that from various sources. I always just move the time up until the date switches, so I know it's past that point.

I broke an eta 7750 based chrono doing this. Won't do that again!

It's true for a Tag, not for Rolex.

Rolex does not use gears that engage to change the date; they use a completely different system.

You can change the date at any time you want with any modern Rolex movement.

Yep, not true for all Rolexes going back at least to the early 70s. It's also perfectly OK to wind the hands back past midnight to retard the date.

Not true for Rolex
True for patek


Although the only incident of breakage I have ever experienced was when I was winding and setting the date of my E serial submariner ... The watch had been in a draw for about a month while a wrist injury was healing, it was purchased new by me in 1991 and this incident was less than 5 years later. ...

I have no idea what time the watch indicated when I began turning the crown but the result was little bits of date wheel splashed against the crystal...

Simple truth is I wouldn't fault the AD for erring on the side of caution... I actually applaud him.

Interesting. I never heard this for rolex so I assumed it was the same for other brands.

[NeoAnderson]

My ad told me same thing.
My wife watch (michelle) was damaged when she tried to change date around 12am.
Book does state not to change date at certain times.

A Rolex will not go broke but I have a rule to never change the date (quickset) between 20:00-04: 00 on any watch.

It's a good rule to have and it's better to be safe than sorry.
