With older eyes I had a hard time finding a watch easy to read and I looked at probably every watch out there. Allot of watches out there but it does me no good if I cannot read it easily! The Momentum M50 I have had for 7 years and the Citizen Eco Drive 2 month’s. Do not know which one I like better? Some days I like the extra features of the Citizen. Other times I like the simplicity of the Moritz Momentum M50.
With so many choices everyone will have a different opinion on there favorite.
Go with what you like all you need is to time the length of your dive and be able to read it underwater easily. Casio and Timex are cheaper if money is a problem then if you loose it diving you wont cry as much.
