Excellent quality watches that can retail for as much as a Rolex, if not higher. The watch authorities are happy to swear that these watches are in the same class as the top of the Swiss line watches, if worse. One model I like is the Grand Seiko, High-Beat 36000. Just a single other producer is making a 36000 beat development (Zenith). Rolex used to purchase these bores for their Daytona chronographs.
