Watches

What is his favorite color, does he like unusual designs (is he a hipster), is there a preference for formal vs. sporty?

If you are new to watches, make sure you understand the difference between a quartz watch and an automatic (mechanical). A good video talking about the strengths and weaknesses of each

Go to the Seiko and pick any you think will suit him. They are all fire and reasonably priced for a gorgeous piece. I have a Rolex Sub Date, Panari Marina 42 Black, grails for some. But I wear my Seikos the most.

Go for one of the Orient Mako 3 options. 42mm, has a day and a date complication, lumed numerals, good color choices, and 200m wr. It also has the same case as the kamasu so if he wants to upgrade the bracelet to something even sturdier he can for relatively cheap. Its a great watch and one of my favorites even over my seikos

If you are in the US get him a citizen eco-drive you think he'd like from the officialwatchdeals store on ebay.

There are some that come on a bracelet like this one. There's also an extra 30% off coupon at the moment for it land some other models.

Eco-drive watches are solar powered so as long as they get some daily light they'll just work for many years. Just don't hide it in a drawer in the dark when not wearing it for long time, leave it on a shelf in a well lit room where it can get some daylight.
