Background information

The 7191 is the second Tanaka style LordMatic watch manufactured by the Suwa factory. The previous model 7190 had a monolithic case. The 7191 looks identical but uses a screw back case and has no parts in common. The design is similar to Tanaka style King Seikos of this period from Suwa, with an elegant dial and clean lines. Seiko offered the 7191 model from 1972 to 1974 in multiple variations. Apart from the classic sunburst dress watch dial (420) there exists a light gray (421), a shaded green gray (428), and a silver linen texture and Roman numbers (480) dial. The dress watch dial is available in a gold plated case (420 SGP). There is a sportier version with dark blue (554), black (556), or shaded green (557) dial. Those models cost less and used the 23 jewel movement in stead of the 25 jewel variant. In 1974 Seiko added two more variants with cut glass crystal: A white (810) and a shaded green with King Seiko VANAC alike appearance (816). All models come with a stainless steel strap. In 1974 this watch cost between 17000yen for the standard stainless steel dress watch up to 21500yen for the gold plated version.
