An Electronika 53V old-school electronic watch from my collection.
The letter "V" means it's water resistant.
In fact, I already mentioned it once on this blog in this post:
Summer mode.
And now a more detailed entry with photos... photos may be a bit dark but they are all I've got.
I have two of them.
One of them has a characteristic plastic strap attached -- I am not sure it is a good idea to dis-attach it ever again (for instance, to facilitate battery replacement).
The other one is separate from the strap yet.
It is in a little clear plastic bag, plus a manual and the strap which you attach yourself..
The case shows names of the world oceans in Russian.
It also says "water impervious" but the Electronika 53V is by no means a diver's watch, more like 30 atm protection, that is, against splashes, maybe, some running water.
The reverse side.
No openings on the back side.
You do everything through the "face", such as battery replacement which I am going to show in photos now.
