In a photo, one of the main reasons why I love Sei In a photo, one of the main reasons why I love Seiko. Two professional diver’s watches, two iconic timepieces of exceptional quality built to last a lifetime. One priced at 7,000 euros, the other at 395 euros. Both proudly bearing the same brand on the dial. A brand with a history like no other, holding the highest number of patents in the watchmaking world. A brand for those who value substance, not just a prestigious name to stand out or feel superior to ordinary people. #seiko #seikodiver #marinemaster #mm300 #seikoturtle #srp777 #hibeatdiver #seikohibeat #watchesofinstagram #seikowatch

I bet many of you have never come across a Seiko D I bet many of you have never come across a Seiko Diver Buddy before. It might look like a toy, but it’s a professional diver’s watch rated for depths of up to 200 meters. This is a late ‘80s design primarily aimed at young boys and girls. #seiko #seikodiver #diverbuddy #diverwatch #1980s #watchesofinstagram #japan
