Russian prototype LED watch. The first!

Post30 Jan 2016, 04:15

I'm interested in history of first digital watches in USSR.
It is well known, that first attempts to make display watch in USSR were at 1973. A year later there were two prototypes - LCD and LED. LCD based on not perspective DSM technology. As to LED version - it is some sort of success. For LCD version the time left - constructors had to change technology for more modern twist effect display, as to LED version - they changed principles of visualisation - from digits of small sqare dots to digits of bars.
Here it is - the first known proto LED watch from the USSR. No info about date of production of this watch. Only well known, that serial watches started in 1975th. According to legend these proto watches were produced for manufactory workers - to test new technology on the wrist.
The pic with activated time visualisation

The quartz brick has its own number (first ones for the first watches marked by serial num, later with the date of production (month and year).
Here the quartz had been replaced during tests or later.

Image

Push buttons are with magnets. As to contacts - there are GERCONES (germetic contact made of glass tube with contacts, placed in the vacuum). There's a row of 5 contacts according to 5 push buttons.

Module of the first LED watch in the USSR.

The plate of the same proto watch, but in ruined condition

Image

Push button with square magnet - to activare gercon. there's no holes in the case for push buttons - it is water proof.

Image

The battery contact on the case back had been welded manually.

Image

Just compare two technologies, there are a few same features to make conclusions, that these watches were made by one group of designers

Super duper...great historic info and thanks for sharing these razor sharp images. I think most led collectors over here are still sleeping or they are getting old M:)W:)M
This is a very special find. I just love it.

Wow :mega:

Never seen that one before!!

Love the big buttons - they remind me of the Zodiac's in shape and style.

I have the common Electronica LED watch but would love one of those - they must be super rare and a working one even more so!

Nice catch :mega:

Great post Andrew very interesting...lots of good things in that module, reed switches, sealed dot display, 24hr time.

Apart from the time obviously what other functions does the watch have.

The line display Elektronika LED watch is one of my favourites as it too has 24hr time.

Yep, even the first Russian digital watches had 24H indication. I've got the only ladies LCD watch of early 1978 with am/pm function - export version. Elektronika 203 w/ 12h format quite rare to find.
DSM proto watch also differs from Microma with 24h standard.
As to this watch - there's almost no info about it. I've met a few cases for this model - NOS replasement cases and... a photo from watch factory museum - with two variants of case for this model (Chrome and GP).

here's a pic from the book, concerning the first LED and DSM LCD watches, designed and produced at the factory.

Image

As to extra functions...
1. 24h time at first push and seconds if you still push the upper button
2. Days and days of week - the lower button

The logic is very common to normal serial LED watches in the USSR. The only difference - the central button (to ZERO seconds ) in serial watches placed ophosite to other buttons - from the left...
Pics of proto case, even not in metal - just in plastic with base 2651 movt inside:

I like the look of the third watch from the left.

The black plastic proto watch what a strange looking thing.

The third one - just a watch, which was under production till the early 90s. The most common model with slight differences.It is based on 2651 caliber (26 mm)
Another quite common model is based on 3051 caliber (30mm). The cirquit block is almost the same - contacts for buttons and plastic base are different.

Image

Image

This one is much more rare to find, based on 3051 caliber (30 mm). It supplied with quite rare for USSR bracelet 22 mm. The years of production maybe 1980-1981. The inscriptions on the bracelet to adjust its lenght - in english. Maybe the watch was produced for export.

Image

As to plastic proto case - i didn't find the watch in metal, so guess not only you consider it strange :)

At least I found the last design of the case, but in steel. The case has no movt, but LCD is real, one of the first DSM with really strange shiny mirrored surface

I found instruction for the watch. So my version has confirmation - this watch is b6.03 like later models. Small quantities of watches were for sale. The price was terrific - 250 roubles. First LCD watches of that period we approx. 105 (chromed) and 120 roubles (Au10).

Image

Image

Driver watch also found papers. It is B6.302 (1977-78) - no confirmation about sales.
