This service covers the replacement of both the battery and 'O' ring,  which are supplied by me and included in the price. You NEED TO to post the computer to me via Royal Mail (RM) Special Delivery (about £7.50), to fully cover the computer. I will then pay for the RM Special Delivery return postage back to you, normally within 3 working days of receipt. Please note that you are NOT purchasing a dive computer (or the case illustrated in the item photos) from me.

Before sending the computer to me you NEED TO:

1. Take four photos which clearly show the all round condition of your computer before you send it to me
2. Make a note of its model and serial number
3. Place your order, then use 'Contact Seller' to enter the above details and attach the above required photos
4. Package your watch well to ensure it arrives and I can return it to you safely and undamaged
4. Send the watch computer to me by Royal Mail (RM) Special Delivery with the correct level of insurance cover

The service provided by us:

1. Removal of watch bevel cover
2. Replacement of battery with new Duracell 2430 (current Best Before date is 2033!)
3. Replacement with brand new 'O' ring
4. Careful air cleaning/fine brushing of visible parts
5. Careful reassembly of bevel cover and clean glass
6. Return your watch to you by Royal Mail (RM) Special Delivery with the correct level of insurance cover (please note, the 10 days postage date is to take into account delays in the item being sent to me as eBay then chase me to post the item!)

Why trust me to carry out this service? Well, I have dived for many years all over the world, from the Great Barrier Reef to the Red Sea - from Grand Cayman (and many other Caribbean Islands) to the Mediterranean Sea - from the Andaman Sea in Thailand to the cold UK waters! Over the years I have changed many batteries with no problems encountered. As a PADI Rescue Diver, I know how important all aspects of safety are when diving - as your very life depends upon it. I therefore ensure all stock sourced is made to the highest quality and can be relied upon to give good, long and safe service.

Please note that I am unable to pressure test your watch/computer, so whilst I will tighten the bezel completely to its original position (as temporarily marked by me before opening the cover), the service is carried out at your own risk.

However, a recent message from one happy customer reads:
"I sent my dive computer to you quite some time ago and you replaced the battery and I got it back. It worked a treat in a few dives I’ve just done in Corfu. Best wishes Brian"
