Some months ago, I went snowboarding for a week with some friends. As every
year, I just wear my Omega Speedmaster Pro during snowboarding. I figured that
a Speedmaster Pro should be able to deal with this quite easily.
However, after a few days on the slopes, I noticed a rattling sound coming

watchmaker put the screws back and my Speedmaster is happy ever since.
