Scuba dude is probably one of the most popular watches from Vostok for a good reason. It’s a good looking watch.
This Scuba dude is different in several ways. The most obvious is the lack of a date window.
There are new Scuba dudes that looks like this out for sale now but this is an old model. There are several differences between this dial and the newer dial. The big lumedots on this older model. The Vostok logotype above the 6 on the dial. There is also no print of the origin of the watch on the dial. It’s a transitional watch. The case is the unusual type 270.
This dial is very rare. I know that there are other variations in the color of this dial. I’ve seen a green dial and heard of a yellow dial. All of them are of course very rare.
