Original 33 mm Size. Sturmanskie, the first watch in space on the wrist of Yuri Gagarin, now offers the opportunity to own the watch that is as close as you can get to the original. This watch is 33 mm. Yes, that is quite small by today's standards for men's watches but that is exactly what Gagarin wore in 1961. The dial configuration is true to the original and the caseback has only the sku number of the watch and the limited edition number. Gagarin's was blank so this is as true to the original as possible. If you are a collector of historic watches or of Gagarin watches this is a must have in your collection
