There Are Pandas, and Then There Are Pandas.
And this isn't either of them! The Pandas we're talking about here, are watches, not bears. And what got me thinking about them (again) was a link posted this morning by @cm.rook who pointed a few of us to the very attractive (and not terribly priced) Yema "Rallygraph" Panda which, in it's most traditional arrangement, looks like the one on the left, but can also be had in the version on the right: The model on the left is a true Panda, while the model on the right is called a reverse Panda. The reason for that distinction is clear--Panda bears, only come in the first arrangement. Now at this point, everyone should be thinking about the most well-know Panda, The Rolex Panda, which is actually a Daytona, and among Rolex Daytonas, the most famous of which is the Paul Newman Daytona, which was famous first, because it was Paul's, and second because it sold at auction for $17.8 million (US Dollars). The story of that auction is well-known so I'll only...

Next I have to assume (once again) that your "Vostok" is the Vostok-Europe Almaz NH35. Big difference here as Vostok-Europe is an entirely different watch company than Vostok. They started out as a company that used Vostok movements in more upscale watch cases, but now use all kinds of different movements. https://www.vostok-europe.com/nh35-320b259/
No debate required. A VSA Dive-Master 500 automatic is a well-known and respected watch among collectors. It is an upgrade over the Vostok-Europe, even with it's Seiko Instruments NH-35 movement. A direct upgrade is the sapphire crystal on the Victorinox over the mineral crystal on the V-E. Swiss ETA movement of VSA is an upgrade from most Seiko-made movements, and there is no watch repairer in the USA that would refuse to work on it, but you might find the V-E harder to find a person willing to service.
Now if I am off-base and you really are looking at the red-dial quartz movement VSA version, then you need to decide yourself if you want a watch powered by a battery or one powered by winding.
