【6138-0031】 SEIKO Speed-Timer Chronograph 6138-0031 Chronograph Blue Square Eyes, Serviced Price: ¥120,000 ➡︎ Guerrilla Special: ¥93,000 【Product Description】 70s Speed Timer Square Eyes 6138-0031. Operation confirmed and adjusted. The dial is a vibrant blue, with a blue outer ring. It's the original dial, and while there's some degradation due to aging, the coloring and the "Chronograph" text are still beautiful. It's extremely rare to find one in such a clean condition; I haven't seen many like it. The calendar displays in English and Roman numerals, which is highly sought after. It's surprisingly clean for a watch from about 50 years ago, but there are some minor imperfections like dirt and scratches around the day display, which is a bit of a shame. Overall, it has a very solid, rugged, and powerful impact, typical of the 70s. The band is also rugged, with thick, durable original SEIKO stainless steel links, making it very rare. The buckle is also marked "SEIKO," making it a desirable band. 【Confirmed and Adjusted Items】 ・Chronograph function (seconds hand, accumulated minute hand start/reset): No problems. ・Chronograph hand reset misalignment: No problems. ・Tachymeter misalignment: No problems. ・Date and day setting change function: No problems.
