Amazing conditions I must say, congrats for the Elektronika 3049. I got one as well, with the ZIM brand. Despite their rudimental construction, they're quite robust, although finding an accurate one is very difficult, due to the aging of the quartz crystal. The yellow reflector panel is one of the most fascinating things of the 3045/3049 series, remembers me of the Seiko 0614 and 0624 series, which adopted the same kind of reflector in order to improve the contrast of the digits in direct sunlight. Can't wait to see your other ones!
