Which Vostok Amphibia? 420059, 170805, 120512 or Neptune 960759
Share




A little diver on the dial. A red-and-blue bezel. A plain black face with no date. Each of these four Amphibias has a detail that gives it its own character, even though they share automatic mechanical movements, 31 jewels and a 200-metre water-resistance rating.
Here is what to look for when you put them side by side.
420059 — the blue Scuba Dude
The little diver is where the “Scuba Dude” nickname comes from. On the 420059, he sits against a blue dial, with a red seconds hand and a date window at three o’clock. The rounded case and steel bracelet finish the familiar look.
That blue is worth a second look. In a discussion about the 420059, an owner describes how much the dial’s appearance changes with the light. You can see why people ask whether it is blue or teal: compare a few of our photographs rather than judging it from one shot.
The listed case dimensions are 39.6 × 46 × 15 mm, with an 18 mm bracelet fitting. If the blue Scuba Dude design is what first caught your attention, start here.

170805 — the Scuba Dude in black
Yes, this one is a Scuba Dude too. The diver is still there, but the black dial, brushed case and black strap give him a different setting.
Look at the broad shoulders of the case. They give the watch a more substantial outline than the rounded 420059. The 22 mm strap fitting changes the proportions as well.
Owners have fun with that combination. One enthusiast shows the 170805 on a yellow tropical strap and describes switching between that, black-and-red rubber and a steel bracelet. It is a useful reminder of how much the strap contributes to the look. Our 170805 comes on a black strap, as shown in the photos.

120512 — black dial, triangular markers, no date
There is a pleasing simplicity to the 120512. The triangular markers give the dial a clear shape, and there is no date window to interrupt it. The automatic 2415.01 movement suits that straightforward layout.
In a forum discussion asking for a clean-looking Amphibia without the Scuba Dude or astronaut artwork, the 120512 is among the suggestions. That gets to the appeal of this model: you can enjoy an Amphibia with a quieter dial design.
We offer it on a black strap, with a bracelet configuration available to order. The listed case width is 41 mm and the strap fitting is 18 mm.

Neptune 960759 — a splash of “Pepsi” colour
The red-and-blue bezel is the reason for the “Pepsi” nickname. Those colours make the Neptune easy to pick out, but take a closer look at the dial too: horizontal lines run across the blue surface, beneath a large 12 and above the date window at six o’clock.
The bracelet joins the case in a distinctive way, which is easier to see in the angled photographs. Between that shape, the textured dial and the two-colour bezel, there is plenty to look at here.
The 960759 even appears in a German watch-forum discussion about Pepsi-style watches, where a participant suggests the Neptune as another option to consider. Its own identity comes through in the details: the dial, the bracelet connection and the Neptune engraving on the case back.
Inside is the automatic Vostok 2416B movement. The factory lists dimensions of 40 × 39 × 15 mm, an acrylic crystal and a steel bracelet.

Which would you pick?
The 420059 and 170805 make the most natural pair to compare: both have the diver on the dial, with different colours, cases and straps. If you prefer a plain black dial without a date, look at the 120512. If the red-and-blue bezel and textured blue dial appeal to you, spend some time with the Neptune 960759 photographs.
For a measurement or a particular configuration, contact us with the model number before ordering. The 170805 is supplied on its black strap; the 120512 can also be ordered on a bracelet.
