Seiko barrel complete for NH36 and 7S26C (Hattori-Seiko)

Authentic Seiko barrel complete for NH36 and 7S26C (made by Hattori, Seiko's parts brand). 

If you're servicing a Seiko 7S26C or NH36 movement, you want to use a high-quality mainspring from a reputable manufacturer. Why take chances with a no-name mainspring that might cause fitment issues with the arbor or barrel, or which might not provide a strong amplitude? 

Seiko barrels for the NH36 and 7S26C are notoriously difficult to open so some watchmakers prefer to just use this genuine Hattori-Seiko barrel complete, which costs only a few dollars more than a quality mainspring. 

Amplitude Watch Parts ships from the USA, so there's no need to worry about long shipping delays or tariffs.
