  1. I've always been so enamored with the Safari that I never even considered whether or not it was lumed.

    Royal Oaks are my favourite watches by far, although I wish AP would be more reasonable at times. Most collectors know that many ROOs are overpriced (e.g. given the less than stellar movement (excluding the new 3120 base)), but when they produce an expensive sports watch without lume, that's taking it too far in my book.

    only $12,500 on ebay...

    Those links aren't showing up for me, but spending that amount of money on eBay for a watch is asking for trouble.

  2. Sorry to disagree but the bezel is same as Rolex Sub and SD bezels just for decompression time.

    The bezel is also intended to be used to measure approximate bottom time, rather than just decompression time. This is the reason why the bezel markers go all the way up to 60 minutes.

    He can adjust the decompression time on the bezel

    You can do that on watches that have a countdown bezel (like the Sinn EZM1), but you can't do that on the Cousteau, Sub or SD etc (which only measure elapsed time and have no minute markers beyond 15).

    This is all rather academic anyway, as divers watches have long since been superseded by dive computers as the device of choice. In fact someone was telling me recently that the bezel on a gen IWC divers watch (I can't remember which model) does not rotate below 10 meters. Whether this is deliberate or not, it means that you cannot use it for deep safety stops.

    Offshore is absolutely right about needing a good working knowledge of decompression limits regardless of what equipment you use, although I would add that the bare essential knowledge is taught as part of the minimum qualification requirements for recreational divers (e.g. for PADI or BSAC qualifications).

    I use a Suunto D6 dive computer, which cost around US$560, although very good computers can be had for much less than that. I personally would never want to dive again without a dive computer and every other diver I have spoken to who uses one says exactly the same thing. As an indication of how important dive computers are seen to be, PADI will not let you obtain the advanced certification unless you have one.

    ps. Offshore sorry to hear about your necrosis, it's a real shame that you had to give up diving.

  3. its purpose is to time your dive so you dont run out of air...running out of air is a bad thing.

    The bezel can be used to time your dive or to time a safety stop, but it has nothing to do with ensuring that you don't run out of air. Your remaining air supply isn't measured by time, but by the air pressure in your air tank.

  4. I also have this problem on my 3717, and I raised it in another thread (here).

    Trust me to be the dissenting voice, but this is clearly not how the watch is supposed to operate, and therefore I'm not convinced it's ok. I do intend getting mine fixed when I eventually get around to sending it in for mods. Until then I will continue to be very careful about how I screw down the crown, because it's not straightforward on mine; I usually have to gently wind it back and forth on the thread with half turns, pushing it further each time until it fully screws down.
