I am fortunate to live near the Ritchie facility. Super nice people and very responsive. 4 years ago, I replaced the capsule on my compass. I forget the model, not a huge one, 4" or so. Anyway, this spring, my capsule was leaking and slowly losing fluid. I checked with them to buy a replacement which is about $80, so not atrocious cost. When their rep on the phone went to confirm what I needed she found my old order and told me that is under warranty so I got a no cost replacement. Stopped in the shop and a very pleasant young lady brought the item out to me. Easy and quick. Good example of how customer service should work. The replacement is a few screws. If you get to that approach,, be sure to get a new gasket if there is on involved on your compass. The fluid is some sort of light oil that evaporates when it leaks out and is such that it won't freeze outside all winter.
