Good question kolosstt!
I didn't have an immediate answer, so I had to study some old CAD files. The first complete watch face is dated 20th August 2011 and shows indeed different numbers: the hands have a round 30° cut while the indices have an ugly 57,21° one. Ugly - to my eyes - both because they look too much sharp and because the cut is different from the hands' one. The oldest CAD file with the definitive 31,79° cut is dated 24th November 2011. This final measure was the result of having made the hands slightly narrower. After this modification they looked so good I didn't want to touch them anymore and I've simply applied the same angle to the indices cut.
Well, it may seem easy, but every damn millimetre takes hours and hours of sweat and tears since me I'm not a corporate design centre: I've done everything by myself, in the spare time and as an absolute self-educated!
Thank you for your interest.
Design coherence
Wow! I don't think I will ever find out this detail unless you mention it.
Fun!
Help?! - ;)
