@ssjedwards and @dhemsley Thanks! I wouldn’t mind the hour being a little larger either but the reason for it’s size is dictated by the mechanical confines. I know of course we can do whatever we want on a digital face and the rules are not constrained by mechanical limitations, but (attempted) mechanical realism is both a big part of the fun for me and a characteristic of the B Sharp brand I like to remain consistent with.
A jump hour indicator of course is a stationary wheel so the display remains upright, but in order for a wandering jump hour to remain upright each individual hour in that wheel would also have to be rotating on its own disc. This is conceivable to me on a larger scale, but I just don’t see it possible in this application. Simply making the font larger is also not possible, you can see the wheel itself is as big as possible in the available space. and when I made the wheel I scaled each number individually to be as big as possible in the opening. The opening itself and the relationship to the numbers is also as big as possible so as not to have the adjacent numbers bleed into view. Like I said, this is all to serve an artificial boundary but it what is the most fun for me because it feels a little more like actual watch making
The pioneer of the Wandering Jump hour complication was a guy named Vincent Calabrese. I believe he always had his wandering hour orbiting more in the outer circumference of the dial, not in a central minute hand assembly like this, but still his hours did not remain upright for the same mechanical reasons I suppose. But his solution was to use the letters S and N in place of 6 and 9 to avoid possible confusion. My feeling was I simply like the look of the numbers better and I won’t usually have doubts about whether it is likely to be 6 or 9 o’clock range
There’s another brilliant contemporary watchmaker named Ludovic Ballouard who has a watch called Upside Down, where each hour is indeed on its own disc always upside down until its turn to be upright. But the mechanics for that movement fill the entire case, I don’t see that happening on an already doubly rotating hour wheel
Anyway, as you have probably noticed, I’m always happy to talk about these things. The decision making process is always very interesting to me.
