I think it's a pretty safe bet, it's one of the midrange brands part of the Swatch Group, so they're using ETA or other well known and durable movements, with a decent finishing quality. It all comes to what's more of your liking. I for one would go for a Seiko, the Prospex Scuba SBDC001 and SBDC007 are two of my favourite "affordable" mechanical dive watches, and if that is too much the SKX007 is a classic.
