This is an awesome Seiko 7A28-7110, the world's first analog quartz chronograph and one of Seiko's finest movements of all time. Extremely well-built and made mainly of metal, this is no disposable quartz movement. It's fully serviceable and extremely accurate. In fact, this particular example has just been serviced by a German watchmaker, and is in excellent running condition with no known functional issues.

A new crystal was fitted. The wear to the PVD coated case was not addressed. The worn PVD has a delightful patina and looks like the rugged tool watch, used and loved, that it is. This 7110 is a rarer JDM-market watch that is hard to find in North America. It is apx 40mm in diameter. Note that this does not have traditional lugs, it's an integrated bracelet. Bracelet is original and generously sized for apx 8-inch wrists. No additional links available. Sold as-is. Described accurately to best of ability at time of listing. Happy to answer any questions. Looking for $400 shipped CONUS but open to offers. PayPal preferred but Venmo and Zelle ok. Some transaction history here, more on eBay, references on request.
