Does anyone know who makes a "countdown bezel" for Rolex subs?

[Xander]

I know this has been asked before, but it was an old thread, so I thought I'd ask again. I am taking the bar exam soon, and we are not permitted to use digital watches. Timing is extremely important, and I would rather see "remaining time" rather than "elapsed time." An elaspsed time bexel would start at 55, not 5, and count down. I am looking for one for a 14060 no-date sub. I know a lot of people ask "Why not just do the math in your head?" To be honest, I am a little dyslexic, and am afraid I am going to make a mistake-it has happened before. Many thanks! If anyone can make me one, feel free to shoot me a PM or post away.
