Vostok Amphibian case(s) comparison

Here's a comparison of most of the current Amphibia cases. Missing are the 060 (just because I don't like the looks of it) and the 960 "Neptune" (which I never bought because of the weird lugs and the resulting replacement strap issues)



Case types from left to right: 420; 710 (ministry); 100; 090 (tonneau); 110


My personal least favourites are on the outsides; the 420 is just that bit too small for my 20cm wrist (also it is a bit tall in relation to diameter) and the 110 is just plain weird, as you will see below. The three in the middle are just very comfortable and I'd be hard pressed to pick a favourite.


So, what's wrong with the 110?
Well it's the only one where the lugs don't curve downward. This makes it ride very high on the wrist with the lugs sticking up in the air which feels weird, looks awkward and is just uncomfortable.

Compare the lug slope between the 110 and 100 case in these two shots:




also the sloping bezel on the 100 is much nicer, giving the whole watch a much more harmonious appearance than the sticky-out bezel on the 110 which looks like a UFO landed on it


Wrist shots from the side:


110 ...I think you can see what I mean



100 ...much better



090 ...very comfy, like the radiussed edges so the case never pinches, also that bezel is class



710... again very comfy with radiussed edges, bit of a UFO thing going on with the bezel



420 ...nothing wrong from a comfort point of view, just a bit small for my wrist and too high for its size

420


Lug widths:
420 = 18 mm; all others are 22 mm

Diameter:
420 + 710 = 39/40 mm ; all others 42 mm

420 and 710 are "classical" designs and have been around since the 60's. These two come with the most dial variants. The other tree are new developments and only come in a few varieties each.

Original straps / bracelets on 090, 100 and 110, the other two are aftermarket

All of them come with a stainless steel case, thick & domed plexiglass crystal and a water resistance of 200 m. All* have the Vostok 2416 automatic movement with 19800 bph, power reserve of min 31 h and a date.

*the pictured 090 and 110 are exceptions, they come with the 2415 movement which is essentially the same but has no date function.
The 110 also is a limited edition with a stainless steel bezel; all other bezels are chromed brass.
