Watches

What's the oldest watch you have? And why?

I sold a variety of Swiss and non-swiss brands for a long time when I worked as a jeweller. At the same time, I developed an interest in antique jewellery and watches.

So whether is cheap or expensive, working or not, 5 years old or 100+ years old, what's the oldest watch you own? Is it a sentimental piece or something you purchased because of its model?

Just hoping to find out about some more different watches out there!
