This is an used vintage watch Vostok "Eared" Amphibia made in 1970s at Chistopol Watch Factory in USSR.

It is rare model with unusual lugs that's why it is named "eared".

The watch comes with a new nylon strap.

It is Amphibia model (200 meters depth) but I have not tested it in water.

I can't guarantee it is water-resistant as all its water-protecting rubber elements are old.

The case is made of stainless steel (except of bezel).

Bezel is made of metal.

The hands and hours indexes are luminous.

Caseback is on screw and crown has got a screw as well.

The watch is in perfectly working order. It is mechanical and needs to be wound once a day.

The watch is used as seen on the images below but runs well and keeps time accurately. 

It has been serviced  by a professional watchmaker: 

1. All parts tested for wear

2. Broken ones have been replaced with good parts

3. All parts washed up in gasoline

4. The movement was put whole, then lubricated and calibrated

5. The case was washed up

Its dimensions are:

Case width incl. the crown - 40 mm

Watch thickness - 9 mm

Lug width - 18 mm
