The caliber 7526 was replaced by the caliber 4R36 (Seiko branded) and the identical NH35 (unbranded) in 2011. They may have kept installing 7526 movements until they ran out. Nothing wrong with the NH35. It's cheaper to replace it than to service it. It's reliable and can be regulated to be very precise and accurate. Because it's an automatic movement it's not for the occasional wearer. You must wear it most of the day or use a watch winder to keep it running. The power reserve is 41 hours when fully wound. People who are inactive will never get that thing fully wound by wearing it. And manually winding an automatic is not ideal.Another option is the Seiko 5, purely mechanical. It will run for many years without any maintenance and never need a battery. It uses a 7S26 movement which is the least expensive of the mechanical movements having good accuracy and reliability.
