I also noticed something strange in the paper certificate (see picture} . It says power reserve 45 hours, but I thought the 1861 movement had 48 hours. Anyone that could comment? I just wound the watch up to the max and will see in two days how long the reserve had hold up.
I was also surprised by the faint omega engraved logo on the center of the hesalite crystal that can only be seen from a angle. Is this on all speedmaster crystals?
