Found time now to reply properly as Friday afternoon is full of free time to spend on what i want and when.
This morning i saw your Sovjet rocket, so let’s write about everything what is fun about your Casio look a like.
When i was a child the Casio was the first watch i bought more than 1 peace. I had a huge counting problem, so the Casio with the calculator was the solution for my problem.
The light was superb, love technology.
Never had the calculator Casio, because i never saw one in a shop. I guess i had only G-Shocks.
The Russians made as you know strange products, and Lada was a car brand of my youth. Still like that cars much, same as i like American cars such as Chevrolet Chevelle 68/69 and Plymouth Barracuda.
Making a U turn to your Technochas CHN-55, never knew such a watches existed.
Clean and fresh.
