The Opinion of Our Watch Expert at Luxurious Watch Review

In fact, Longines did a great job on the design of this tool watch and offer a finish that also makes it a perfect every day watch or even a sophisticated watch to go with a suit. This is indeed a typical diver’s look and feel these watches have with their huge luminous hands, clear contrasting dial and uni-directional bezel. If you are looking for a cheaper yet sophisticated watch, you might want to check the La Grande Classique Presence.
