I'm looking for a high quality waterproof watch that can be visible after days in the dark,  luckily just before I clicked 'buy' on this economical Submariner by Rolex I saw it was only 'luminous'.  You would think for that kind of money they could afford Radium or Tritium.   !   POS I guess.  The best I've seen is the Luminox Navy Seals with tritium tubes.  (While the only decent 'luminous' was the Invicta automatic that did hold light for over 12 hrs).   I'm still researching.  Almost sold my house to get the Rolex, but it's just not good enough.  Any suggestions?

There are not many companies making tritium lume watches; all the current ones use miniature gas filled tritium tubes, as far as I know. That means the ones with glowing digits rather than indices tend to be larger sizes.

 

Ball make both lower and higher end ones:

https://www.ballwatch.com/global/1/collections/roadmaster---94/marine-gmt-ceramic---dg3030b-s1cj-bk---2639.html

Traser make more mid-range ones:

There are some others, but those give a range of examples.

Tritium fades quite quickly over time; it's half life is roughly 12.5 years, so a 25 year old watch would have 1/4 the intensity compared to when it was new.

If it must be tritium, then I'd only get new or very nearly so - no vintage ones.

You can add MWC, Marathon and Nite to that list, they have also sold T100 tubed watches as well as the more normal T25 tubes. The tubes at very best will only last about 20 years but these three and Ball do replacement services.

Unfortunately the periodic table is complete, so either something like radium which is bad for your health and isn't available any more or tritium, witth it short half life, as far as brightness is concerned.

I've run across a "STAUER"  tritium watch that seem pretty bright.   I'm looking at a Marathon as well.   I  had hoped a Radium dial watch would still work but I think all the old Seikos with radium have burned up the luminous material by now.  The Ball watches,  maybe $1000  ,  um  wow  certainly better than Rolex but 3 times the price of a Marathon,  couldn't be worth it.   (for my worst case scenario we're hunting,  rainy,  no chance to charge a lume watch,  someone is injured at night.  I want a watch I can check pulse,  hold pressure on a wound for 10 minutes ,  mark a tourniquet etc.)  (and it still works after I've shot my 12 ga. and fell out of a tree).   I am having so much fun investigating, collecting and repairing watches !!  Not ready for prime time but watches are cool.

    • Alex mentions the coils below the stud should remain the same as you move the regulator block along the terminal curve.  Mine do that. What he doesn’t discuss and is used in the other video is how the regulator block is used to adjust rate and positional error.  He also doesn’t mention how opening and closing the pins could and in my case does, alter amplitude  In Alex’s video once he sets the stud he never adjusts the regulator pins yet every new movement I get have the pins signing closed. 
    • The video I linked above does mention the spacing of the hairspring coils, and the importance of the regulator being able to move through its full range without distorting the hairspring - the terminal curve of the hairspring must be concentric with the regulator pins throughout the regulator’s range.  If you meticulously follow every step in this video, the regulator system should behave as intended, regardless of the brand of the movement.  Best Regards, Mark
    • Hi friends! My mother got a bunch of old watches from a horologist who was retiring, and he subsequently passed away. It's been in her studio for years, and she showed it to me today and I just fell in love with it. Sadly, I don't know a darn thing about it yet. It's quite old, or at least seems to be. It has two winding arbors, but the key is missing. The crystal appears to be some kind of yellowed plastic, which is odd- I think it was replaced at some point to possibly protect it or something. If I had to guess, it's from the mid-19th century, given that it has no keyless works and that it says "Anchor Escapement" in French. It looks to be about 18 ligne, and the case fob is positioned in the upper right corner. The face is missing the dial, the hands, and a couple of the wheels that drive the hands- I think. But the movement itself seems to be in excellent shape. The serial number on the movement matches the number on the case- it's stamped on the movement and on the case in two places. I haven't started any disassembly yet, but I'm wondering if anyone can give me some idea of what kind of movement it is, and where I might look to see what parts are missing from the face. i may even have a dial that would fit it. It's in good enough shape that I think I could get it running, assuming I could find the missing parts. Any insights are vastly appreciated and thank you! Addendum: The inside of the case has some *very* tiny scratched numbers and letters in it, but I am having an extremely hard time seeing what they are. Like "N 99" and "No192X", They were clearly done with some kind of sharp stylus and maybe they mean when it was serviced or by who? Addendum the second: At least one of the scratches seems to say "N1921X" or maybe "W1921X". Serviced in 1921? And the inside lid of the case has the letters R H with a star between them, and a very tiny mark that says "ARGENT" in a u-shape.
    • I’ve watched every video I can find on YouTube. Some of the info is contradictory and none mention  the effect on amplitude or spring coil spacing which I observed. I was hoping someone here is a Seiko expert and knows these inside out.   
    • This video explains how to set up and adjust the etachron regulator :   I hope that helps, Mark
