From the CW Website;- "the moon is linked to the hour hand and is in constant motion, with the phases of the moon represented in a single smooth movement."

Thinking on this; if you stop the hour hand i.e. when you hack the watch, you will also be stopping the Moonphase disc BUT that is synchronised to the hour hand; a bit like the GMT hand on a GMT movement that rotates through 360 degrees once every 24 hours, except the Moonphase disc in a JJ04 Calibre does a 360 degree rotation once every 59.06 days (29.53 x 2 days as there are two moons on the disc).

As for adjusting the Moonphase disc if you've left the watch stopped for any period of time (as I tend to do) the Owners Handbook states (actually from the C1 Moonglow, but the C1 Moonphase will be the same);-

"Setting the moon phase is relatively simple. For perfect synchronization, you will need the date of the last full or new moon. To adjust the moon phase pull (the crown) gently into position 2. Turn in an anti-clockwise direction to rotate the moonphase disk into the desired position. Rapid correction of the moonphase is possible at any time without risk of damaging the mechanism."

Remember, the movement used is a JJ04 modification of the SW220, which is a day / date movement.

Finally, another point to remember, is that most moonphase watches have the moonphase in a small subdial, with the moon's position advancing in daily steps (a bit like the date) as opposed to the JJ04 where the moon advances smoothly and perpetually.

I hope this helps.

Without an actual date on the watch won't this be difficult to get perfectly in sync?

On the Moonglow, the date and moonphase are adjusted independently.

After thinking a bit more, I get your point, even though I’ve never set the moonphase to a date and rotated the hands through days to get to today. I’ve always followed the “ballpark it, then adjust on the next full/new moon if needed” strategy

I believe I’ve read that the Moonphase isn’t designed for precision, hence the lack of indices (but it still has a seconds hand for some reason)

Probably; although it depends on the method you use to set the moonphase and how perfectly in sync you want it to be.

The long, but perhaps more accurate, way (to my mind) is to set the Moonphase disc to the Full Moon position, look up the date of the previous full moon and then wind the hands forward the required number of days to 'today'.

Alternatively, as I would do, I'd look up the last full moon or new moon date, make a note of how many days ahead 'today' is and then advance the moonphase disc by the required amount (accurate within the tolerance of my eyesight and estimation of how far to move it).

Whatever works for you.

PS> It looks like initial stocks have been taken up as the website is now showing 'Pre-Order'; although as Mike France told us in the Zoom Preview, the next batch is not far away, specifically November 10th.

Belay there it looks like my account and cookies are playing tricks on me. It's actually still 'in stock'.

Another option: wait till the next full moon to set it!

Or if you don't need it exact, use this website and eyeball it: https://www.watchnetwork.com/moonphase/

It's all moot to me as I keep mine on a winder

Assuming the crown's "date change" advances the Moonphase a days worth at a time (so 29.5 days from full moon to full moon) then I presume you set the moon to either new moon or full moon, check a calendar and then advance the Moonphase however many days you are past the new moon/full moon. Then you are ok for 128 years.

My cheap Moonphase sets like this. You set it to new moon (say) with no visible moon disk, and if you are 10 days (say) past new moon, you advance the Moonphase by 10 clicks. With mine, it's a case side pusher, and I use a pencil or ballpoint.

It's really cool that in normal operation there is no daily jump or even hourly jump, but a very very slow progression of the moon disk.

The watch is not one for me. But I appreciate the effort to find what appears to be a moon phase wrist to promote it.

This is a long way from being a watch I'd want, so it's one to admire on the wrists of other, more elegant folk.

Love the case, gives me old C9 vibes. Would already be ordered if I wasn’t waiting for my dinging watch to arrive in Nov.

I quite like the new C1 Moonphase. I like the whimsy of no indices and the metaphor for pre-modern times of telling the time/date by the moon. The dial looks very good in real life too. Is it for me? No. I have a C9 Moonphase that has scratched the moonphase itch for life. As a whimsical dress watch it fulfills its design brief perfectly. It's a dress watch which you shouldn't expect to be legible. It has the expected CW cleverness through the use of Globolite and twin aventurine disks. I hope it sells well for them.

It always amuses me when CW talk about there moonphase being accurat for one or is it two days over 128 years. As the moonphase is driven by the movement then a quick calculation says that the the watch would have to be accurate to about 3.7 seconds a day just to be within 2 days over 128 years. The actual answer is a bit lower as I excluded leap years but will a watch run without attention for 128 years. I don't think so.

On the Moonglow, the date and moonphase are adjusted independently.

After thinking a bit more, I get your point, even though I’ve never set the moonphase to a date and rotated the hands through days to get to today. I’ve always followed the “ballpark it, then adjust on the next full/new moon if needed” strategy

I believe I’ve read that the Moonphase isn’t designed for precision, hence the lack of indices (but it still has a seconds hand for some reason)

Is it that we crave the reassurance that everything is still functioning? (I think about The Beast C60 chrono with its "spinner" to show that the time is passing by at the approved rate.)

UPDATE early doors Friday 27th October: I see that overnight both versions have slipped over into Pre-order.

That, or some belief (that may be entirely justified) that people who are looking for an automatic watch want the sweep because otherwise, why not get quartz.

I think only having SWISS MADE is also silly but I assume it’s also a belief that it’s not enough to be Swiss Made, but that it also needs to be on the dial.

surely if people 'did their research' then 'Swiss made' wouldn't have to be put on the dial.

I agree completely, you could put it on the case back if needed

On further reflection, the Twelve Halo doesn’t have a seconds hand and I believe the Moonphase shouldn’t either
