Besides different metals, are those 3 different dials as well? I can see the middle one is a pulsation dial, is one a telemetre dial and the other a tachymeter dial?
All the Best Alex,
and you 2 Alex, what a great trio to look forward to, thanks you for your thoughts and hints,
A lovely trio, Alex!
Enjoy the week-end.
While I am not really into chronos, I have to admit that I can not help myself admiring this trio. Thank you for this Alex
