Confusion? No confusion that I understand. Both have the advantages and costs. Dive watch can be worn every day, is easily seen and can be used for diving for basic timing. A Computer can’t be worn as a daily watch (to big), visibility varies depending on display, and used as a dive manager, lots of features.
The OLED dive watch I inquired about, would be easily visible in all types of situations, due to it’s clarity and display and even have an analogue watch display, just as the Apple Watch does. The OLED watch could have minimalistic features like dive analogue dive watches today, or ramped up to contain all type of features, but the complexities of expanded features would make that watch more like full featured Dive computers today which is higher in cost and larger in size.
I expect OLED dive watch existence is inevitable, but when?
