I can understand why it's not their cup of tea. Maybe its the fact of a damaged dial. Tropical can be a very broad term used to describe a color change in the dial and often time I've seen used on dials that have the slightest and darkest hint of brown. Is there a color change? Sure! Is it worthy of being coined with the term Tropical in my book? Maybe not.
For me, a true tropical should have perfectly even color change, no water damage, lume plots all full, and print perfectly bright and legible. I am a fan of the light caramel tropical browns out there and what some term Super Tropical!
Simply put, a true tropical should look stunning to the eyes....naturally aged in its purest form.
