Flip cover watch. More common for old ladies' pieces, to make them look like bracelets. Sometimes called "surprise" watches. You should post a photo.
There are some similar concepts for men's watches as well - the Piaget Coin Watch is one that comes to mind. I feel like it would be cumbersome to open up the watch whenever I wanted to know the time.
Also (though a little different) are Braille watches, where the crystal flips open completely so the user can feel the hands.
No, but some links point elsewhere on the internet to auctions or articles that may expire for various reasons. One of the great things about Omega Forums is that it's a repository for information and any photos loaded onto the site remain in perpetuity. This makes Omega Forums a great reference source for watch nerds and horologists. It's better to have reference photos than a horde of useless expired links.
An interesting watch to be sure, but I cannot "like" a watch that destroys pretty old coins for its creation.
Early on Blind watches were simply hunter case watches with the crystal removed. It took very sensitive fingers to figure out the time without breaking or bending the hands. I've seen a few of these from estate sales on Ebay in the past.

While the dial certainly has plenty of patina, the manufacturer name can be read to be Bucherer. A bit of image searching reveals: https://wannabuyawatch.com/product/bucherer-lemania-817-chronograph-circa-1960s/
while i've seen dates given their own spot where the register is (70's lejour to name a few), or should be w/o the chrono function. i've also seen dates carved out on the dial later with an exacto knife just so they could utilize the date feature of the movement installed. i can't believe i've never seen seen this one. to implement a date feature like this has to be the work of an idiot with zero design skills.
