Seiko Crown Special 15021 80 microns GP 23 jewels excellent condition

Description: The Seiko Crown was introduced in 1959 as Suwa’s replacement for the Seiko Marvel, featuring their first fully in-house movement. However, it was the 1960 release of the revered Grand Seiko 3180 that truly left its mark in Seiko history. Interestingly, the Grand Seiko was directly developed from the Crown, and the two share a significant connection.Now, let’s focus on the Crown Special, which emerged after the development of the Grand Seiko 3180. Think of it as a regular Seiko Crown on Grand Seiko steroids! Here are some key details:Caliber 341: The Crown Special features the 341 caliber, which includes diafix-jeweled bearings for all wheels in the going train. This results in a total of 23 jewels, falling between the Grand Seiko’s 25 jewels and the regular Crown’s 19 or 21 jewels. The extra diafix cap jewels enhance accuracy and reliability by maintaining optimal oil levels and preventing contamination.Fine Regulator: While the Grand Seiko boasts a tadpole fine regulator on the balance, the Crown’s balance has a regular coarse adjuster. The tadpole regulator simplifies fine adjustments during regulation, although it doesn’t inherently make the watch more precise.Train Bridge and Finishing: The Grand Seiko’s train bridge is individually numbered, a feature shared with all Seiko chronometer-grade movements. However, the finishing on the Crown Special’s bridges is slightly lower than that of the Grand Seiko, with polished bevels and attractive graining.In summary, the Seiko Crown Special offers vintage Grand Seiko vibes at a fraction of the Grand Seiko price. It’s a remarkable piece of Seiko’s horological heritage!
