Seiko SPB187J1 Prospex Diver Automatic Blue 42mm – Code SPB187J1

Professional diver's watch from the Prospex line, designed for real-world use in water but perfectly suited for everyday wear. Its highly legible deep blue dial and compact construction make it less bulky than classic diver's watches but just as sturdy.

The 6R35 caliber offers a 70-hour power reserve: take it off on Friday evening and it's still running on Monday morning. A solid tool watch, not a showcase object.
