Review: Watch battery and o. Ring - Just what I needed for my dive watch.
Review: Replacement went without a hitch - Exchanged the battery on my Suunto D4i. It could have been a disaster but actually it was extremely simple and the watch hasn't leaked so far on the 5 dives I've done since changing it. It's a risk but one probably worth taking given that a professional battery replacement is so expensive.
