Diving equipment can be expensive. We try to cut corners where we can. Some things like a new drysuit which can run to over £1000. We won't spend that much, but it is easily done. We will buy second hand diving equipment from eBay when we can I have been pleased with almost everything we've had from those auctions.
A number of years ago, I needed a new dive watch. The one that I had died just before we were due to go on a dive trip. Water got in the watch - and salt water and watch works just don't make good companions. It was just after a battery change - done at a jewelers that reported to test the security of the seals if they change the battery of a dive watch - that my watch had died.
We were going on a trip very soon and I needed a watch that I could take with me under the sea. Just out of curiosity, I looked in the catalogue of the local supermarket. They had a Lorus Sport Watch, rated to 100 meters for about £12 pounds. Whoo hoo! Even if it only lasts a short time, it is a better price than the near £300 that the dive shop is asking for a watch of a similar rating.
I'll get another battery for mine but I'm afraid that the other watch is dead. I can't complain too much. We've had very good service out of those watches for not a lot of money. I am now watchless until I can find time to get a new battery for my watch. My left hand feels weird and there is a white bar across the wrist. I feel adrift without a watch. I may look at new watches - as serviceable as those watches are, they are NOT very feminine.
