Sky Dweller Month Setting

[No SUBctitute]

Before I ask my question, I wonder why Rolex doesn't have on its web page (https://www.rolex.com/watches/sky-dw...6934-0003.html) a description about the month function in the text where the other functions are described. This is an amazing complication and it seems like Rolex would tout this loudly. Additionally, the power reserve of 3 days is a decent feat that I think Rolex should prominently display. Instead, we get a para on Rolesor (yawn) and a long para on the bracelet (double yawn, wake me up when it gets glidelock). Although, apparently, Rolex marketing is working just fine, so what do I know.

Anyway, my real question is, how difficult would it have been to create a movement that accounted for February's 28 days rather than the owner needing to adjust the date at the end of February?

Big difference between an annual calendar and perpetual calendar, I would think.

Annual calendars require date adjustment once a year at the end of February. What if one could be designed that had 28 days programmed for February. Just like March has 31 days and April has 30, every February would have 28 days.

This way the date would have to be adjusted manually only once every 4 years. During a leap year, on February 29th, the watch would jump to March 1st, so both the month and the date would need to turned back. But, again, this would only have to be done once every 4 years.

Exactly. That's what my non-horologically trained self didn't understand.

What are the mechanics of the movement differentiating between month with 30 and 31 days, and how difficult would it be to make the movement treat one out of the 12 months in a third way--28 days instead of 30 or 31.

I can't picture how the movement works and understand the difficulty of such an undertaking.

The good news is that at least you didn't ask why would anyone want to know what the month is as several others have. It's a terrific watch!!!

BAHAHAHA. Good one.

It IS an amazing watch. It wasn't until after I watched the Rolex animated instructions on how to set it that I really appreciated it.

I received mine on 8/10. Strangely I missed the midnight change of the month this past month so I didn't get to watch it all change. I'm looking forward to the Sept./Oct. change on the thirtieth to watch the change of month and the date switch from 30 to 1. I guess I'm easily amused.

This is where things get interesting; I have a $300 Citizen with a perpetual calendar. It's all analogue, with a couple of sub-dials, and it changes from 28th February to 1st March and every leap year, it shows 29th February. It's about the same thickness as my Daytona.

It's the sort of thing I would do even although I'd most likely wait until the month change fell on a Friday or Saturday night. Midnight is way past my bedtime on a school night

Actually, can you post a video of it when it happens? I'd love to see it

Good idea; I'll see if I can catch it on video!!! I work nights and am rarely asleep at midnight so it should happen naturally enough for me.

It does.

But you have to look for it

You shouldn't have to look for it. They should be preaching it loud and proud!
