TravelTec was my first. What a beast of a watch! Red Gold ScubaTec is special because it's 1 of 5...love that watch! I also picked up a stainless blue ScubaTec as a daily driver. Rock solid! So the count stands at four so far with more on the wish list (My grail is a gold FourX!). I REALLY want the ScubaTec Manta Trust before they sell out, but my budget is now focused on a pair of TAG Heuer's I need to get in the next few months. Let's see what 2018 holds!
