Freestyle Hammerhead Battery Change?

[dlndavid]

Anybody had any experience/advice on a battery change for the Freestyle Hammerhead dive watch.
It almost looks like the back cover may be threaded on and can be removed with the proper spanner wrench.

You do need a spanner wrench to open it, it is threaded. By the way I love that watch. Have mine for over a year now.

I was able to remove back cover, remove battery, cleaned o-ring and o-ring groove. A microscope helped out alot.

Now I need to get the battery p/n SR621W Maxell, and it looks like it is very special, only two other cross references

SR626W 376 376 MA 376 619 SB-BW 280-72 SR66
SR621W 280-70 SR60
SR44SW 303 D303 303 A V303, V521 303 SB-A9 280-08 GP303 SR44
