In my opinion, if we are talking about the most “Japanese” watches, few others beat The Citizen, specifically the ones with indigo dyed washi dials. Which country is known more for its selvedge denim, and washi paper obviously originated from Japan. The practicality of solar power, durability of titanium, and the high accuracy movement is so characteristic of products from Japan too. It is also finished to a level reflective of great pride in the product. This specific reference is the AQ4100-65L. It is one of my grails. Can you think of more “Japanese” watches than these?
