As with any other merch you might look into at any given point (especially gadgets), in most cases, the cheaper models are not as good as the original. A price bump is almost always justified when you look into it and do a proper product comparison. When it comes to dive watches, things are the same. The more expensive models benefit from more features and enhancements that make them worth their price tag (especially if we’re talking about vetted ones like the best dive watches under 1000 dollars featured in our top above).
That disclaimer being said, it doesn’t mean more expensive is better for you. Depending on your current skills and status, perhaps you don’t need the fanciest model yet. In many cases and for most beginner and intermediate divers a budget dive watch will do. Also, in the case of really fancy brands which enjoy cult status, you might pay a little bit extra for the prestige which comes with the name, too.
