Years ago I went through a vintage LCD watch phase, mostly the Seikos of the 70's, at some point I must have picked this one up, a Sekonda LCD, it must have sat in my watchbox for 15 years at least, I came across it today looking for something else and it occurred to me that I had never looked at it properly, certainly never tried to open it and see if it worked, so I did today, inevitably one of the cells had leaked so I wasn't hopeful of a result, however, its alive! very basic display, hours and minutes only, 3 recessed buttons but only one seems to do anything, it advances the time very slowly to set the time. After doing some Googling, it appears to be a 1977 'big block' Sekonda with the first Russian LCD movement the B6-02, this was introduced in 1974 and put in a variety of cases over the next few years. Its quote chunky, 37mm x 45mm by 14mm tall, Ive only found a few references to this style that Ill link below. To have fired up after all this time after a leaky cell is quite impressive to me.
