An in-house automatic that both hacks and hand-winds, under sapphire, with a screw-down crown and 200m — at a price where Seiko is still fitting Hardlex. On specification alone it is the strongest watch in its tier on this site.
41.8mm across, 12.8mm thick and a published 46.8mm lug-to-lug, on a 22mm strap. Three years of warranty, and Orient is sold and serviced through normal channels.
Orient publishes no US service price, so an eventual overhaul is a quote rather than a number, and the 40-hour reserve means it stops over a weekend off the wrist.
On paper this is the best value in the category and it is not close: sapphire and a hacking, hand-windable in-house caliber at a price where Seiko still fits Hardlex. Orient's three-year warranty is longer than Hamilton's or Tissot's.
