You missed the one and only best mechanic chronograph in the market the Sea-Gull chronograph known as 1963 or D304 with ST19xx caliber based on Venus 158 who was sold by Swiss to Chinese. A chronograph which was used by PLAAF pilots. Though Baltic wears the ST1901 caliber.
2. And how could we forget to mention Citizen. They are absolutely fantastic price/value solar-driven chronographs, from as little as US$200 all the way up to even US$1000+, many dozens of models to choose from.
Let's cut to the chase. For a chronograph to be of any practical use for dead-reckoning low flying navigation , it has to have a totalizer with 12/60 minutes dials like the ones on the old German Luftwaffe Type B Flieger watch; that is, an outer dial of 60 minutes with one minute intervals and an inner dial of 12 hours. Some Seiko chronographs with a 7T92 movement has those dials. One can buy one for about 100 bucks... All the rest are obviously beautiful watches for your collections.
Since you mentioned the Baltic chrono which uses the Chinese ST19 movement why not the OG?? The 1963 chrono which you can find all over Ali Express for under $200.
I am flabbergasted by the fact you missed the most iconic Bulova Lunar Pilot! You just lost 1 subscriber and 1 loyal buyer from your website. I am saddened by this fact and that I can only assume your "paid" videos are made, sponsored by those watch makers. Shame on you!😤
Hey! Thank you for shouting out the Lunar Pilot. We unfortunately can't include every watch fitting the description in a short video. My first vintage watch was a Bulova, so I'm personally a fan. Also, this video is paid for only by Chrono24. Brands don't promote secondary marketplaces, and we wouldn't be able to feature vintage watches if we were being paid to promote their current inventory.
3. Last (but the list could/should be continued of course) there is the newest Orient Mako Chrono /solar series. (also called Neo 70s) like the already-famous WV0041TX They also have a more classy series "Classic" like the RA-KV0402S10B Or an earlier/cheaper series called "Sport" like the RA-KV0002L10B
