Rolex testing!
Today while surfing the net, I stumbled on a lovely 1930 Rolex Cellini Brancard full set!
The condition is far from perfect but very charming.
While looking at the warranty certificate I noticed something I never knew before.
Other than being tested in different positions, it was also tested in the refrigerator!!!
Nothing special at today’s standards, but in 1930?
I’m very impressed!
Pushing the boundaries even in the early years!

I must confess!!!
Back in the day when I owned my Datograph prior to service, I did a fridge test and it felled, but that’s another post... 🤫, don’t tell anyone;-)))
I remember that almost all vintages watches i own have the writing
"Heat and cold adjusted". But those are cheap ones, idk what cold really means. A very nice find! Thank you for sharing!
My pleasure.
On modern watches I knew the meaning, but I wasn’t aware that Rolex did this test in those early days, considering that the watch isn’t water resistant!
