Mares M1 - missing O ring HELP!!

[Sirto]

I recently purchased a used Mares M1 computer and found that it is missing an O-ring in the battery compartment. I have contacted at least 5 different dive shops including several Mares dealers and the offices of Mares trying to either order an O-ring or get the info on the proper size. It's amazing how little cooperation you get from Mares. Mares went as far as giving me a part number (46110225) but said to go thru a local dealer. The dealers around me are not authorized Mares dealers and the authorized dealers either would not take an order to be sent out by mail or had a large minimum order size. None of the dealers were able to give me the correct size.

I went to the local hardware store and picked an o-ring that seems to fit well but I sure would like to have some verification that it will work before I go away on a two week dive trip to Roatan in October.

I used a 1/16" thick O-ring with an ID of 11/16". What I'd appreciate learning form someone is:
1. Does this computer use a simple o-ring or some other type of seal (the cap of the battery compartment is oval but the o-ring does appear to stretch to fit)?
2. What diameter / thickness o-ring (if that's what it is) does Mares use?

I'm hoping that someone with an M1 or Dacor Dawin (same computer) will check their unit and reply.

Thanks

Why don't you just contact whoever you purched it from, and have them give you the part??

I've tried that but so far without success.

Where did you get it?? Why not just send it back as defective - and get one that works somewhere else??

Sirto,

Mine measures 1/16" by 13/16" (center-to-center) so you're in the ballpark.

Great, thanks for the feedback. I feel a lot better about it now.
