■ Buyer's comment

This is Fujimuro. CA4665-59L's blue dial grabs your attention. The deep colors that change their appearance depending on the angle of light go well with the instrument-like surface. Eco-Drive x 20 ATM water resistance gives you peace of mind, and the crisp 1/5 second chronograph movement also feels great.
When you wear it, you feel like the sky is getting closer. Coupled with the special feeling of being limited to 900 pieces, this is a great piece for both your collection and your daily life.
