Aqua Terra will not be in this list because they are counted towards GADA watches. Need to be strict or else the list will be hella long.
1. Seamaster SMP 300 white
Iconic watch. White version has an excellent contrast mostly thanks to the wavy pattern and the subtle black outlines. Looks all white at a glance but then it's not.
2. Zenith Chronomaster Sport
Yeah yeah yeah, it looks like 116500, whatever. That is indeed a good looking design. Wouldn't say this Zenith "improves" on that design, but to me it's equally great. To me, the tri-color subdials do give the watch a bit more flavor. Functionality-wise this watch is also impeccable, completely dominate the Daytona by a landslide.
Oh and the caseback. Did I mention the caseback is the most beautiful caseback in all of diver realm?
3. Oris Aquis, the entire freaking series
It is the sunburst dials. I will be completely frank. The way they did the sunburst dial in this series won my heart.
They did so many colors so well it's insane, and they weren't afraid to experiment with different type of bezels.
the Cherry is with a brushed steel bezel, the typical blue and green are with shiny blue and shiny green bezel, there's also Tungsten.
Coupled with gradient dials on some of them, it's hard to not hand Oris the award.
Calibre 400 makes it a bit expensive above 3K MSRP but they are a great combination of textbook diver + amazing dial color and bezel combo.
