For me I've been collecting (mechanical) watches for 20ish years. Half my collection is high-end Swiss watches, and the other half is more ecclectic but I have a real soft spot for the former Soviet designs.
They were not expensive, and even now you get a great watch for €50 because they made so many of them.
Although the focus of the USSR watches wasn't that level of quality you see in the Japanese pieces they're so rugged and simple that most of them will outlive me.
I regularly buy 50+ year old watches that have never been serviced and still run properly. Obviously there's some element of survivorship bias at play, but the engineering there is top-notch.
