Grand Seiko Sport Spring Drive Watch SBGA463G
The Spring Drive 200m Diver’s watch has long been appreciated for its precision and robustness. This version features a case made of high-intensity titanium which is lighter than stainless steel and more resistant to scratches. To ensure that the time can be read easily and without error at a glance, there are 60 distinct markings as well as five numerals on the bezel. Each hand is different in design and stands out clearly from the dial.
