A beautiful dial (and back side as well :-) There seems to be no info on their website, so here's my guess on the 5 hours and 20 minutes:
Since 5h and 20m is 1/(4.5)=2/9 of a day, choosing this cycle means that the moon will find itself on the opposite side of the dial at any given time on any two consecutive days (e.g., perhaps romantically, if you see the moon at 12 o'clock at 9pm tonight, tomorrow at 9pm you will find it sitting at 6pm, and so on).
Given that there are 24 x 60 x 2 minutes in two days, to create this effect using a cycle measured by a "round number" (5h and 20m looks pretty round), you need to divide 24 x 60 x 2 by an odd number. Its odd divisors are of course the same as the divisors of 45 (namely, 1, 3, 5, 9, 15, and 45 itself). Given this, they chose 9 among them, which is probably the same choice I would have made.
For instance, if they chose 15, there would have been 7.5 cycles a day, each of 3h and 12m, but I guess 5h and 20m is even more round ;-) The number 3, yielding 16-hour cycles, was of course a very good choice (but perhaps too long).
Again, this is just the first guess that comes to mind to a PhD mathematician on vacation in Italy (whose methods used here can be figured out even to a third grader...
), so please check with the Barcelona brand if this is indeed what they had in mind! If they do, then I deserve one of their enamel watches... Cheers.

A significant number?
Am fascinated by the products of Atelier de Chronometrie in Barcelona, not least their #4, which has a dial that rotates every 5 hours and 20 minutes. Why is this number significant, please? ...
Its a spanish working day....
đ€Ł.... Joking... i have no serious answer to that... great watch though...
Hahahaha
Thats what i also thought... must be the week working hours đŹ. Siesta ole!
Comment of the week
Hard to find such a short-sighted and stupid comment in the forum. We have a new clown
The only reason seems to be "poetic", according to the website....

If there is no reason then surely with a bit of effort once every 24 hours would make more sense? [nt]
Becomes a day night indicator then which would be ideal.

I love that explanation.
Itâs not often one reads several paragraphs of perfectly good English and yet understands not one word. Iâm going for a lie down now. đ€Ș Regards Kev.
For a decade I was engaged in 3rd grade math
Actually in production of textbooks for Kindergarten to 6th grade â elementary arithmetic, geometry, algebra, etc. (quite ironic given that the last formal math class I took was in high school in 1967) But I suppose to the old sayings âIf you canât do it,...
The owner of the watch can decide the duration of each rotation, since ADC is all about bespoke.
I asked the same question when I met with the founders of ADC (lovely people by the way). The rotating dial is a romantic feature anyway, 5 hours 20 minutes is just about the right amount of time to keep the dial interesting when viewing it at various tim...
I guess so, but the moon position wouldnât always be âcorrectâ.
Personally I also find it more romantic that the dial rotates âspontaneouslyâ, Ken
The dial is basically a 50-50 day/night dial (moon position is simply showing in the night zone), this makes it an ideal day night indicator. Works exactly the same as the day/night ring on Patek WT's. [nt]
Can't see anything romantic about something that means nothing.
I read all of this now, but then Iâm sure Iâm following what youâre looking for: was your question âwhy is the choice of 5h and 20m significant?â or âsince I donât understand the 5h and 20m thing, how can some people see something romantic about it?â
The second is certainly easier to answer, but please at least understand they are two very different questions...and you seem to move a bit too fast between the twođ
