Throughout its long and storied history, Seiko has teamed up with various disparate entites to release commemorative watches - like this gold 1996 Seiko 7N01-6D30 "Joshinetsu Expressway" dress watch, with original Seiko 7N01 instructions manual. 
 
Why do we call this a Joshinetsu Expressway watch?  
 
Kanji Japanese engravings on this watch's caseback identify it as gifted to commemorate the completion of the Sekikawa section of the Joshinetsu Expressway.  
 
The Jōshin-etsu Expressway (上信越自動車道, Jōshin'etsu Jidōshadō) is a national expressway in Japan. It is owned and operated by East Nippon Expressway Company.  The first section was completed in 1980 and the entire route was completed in 1999.
 
Jōshin-etsu (上信越) is a kanji acronym consisting of 3 characters, each representing the former names of the prefectures that the route traverses. Kōzuke Province (上野国) consists of present-day Gunma Prefecture, Shinano Province (信濃国) consists of present-day Nagano Prefecture, and Echigo Province (越後国) consists of present-day Niigata Prefecture.
 
Officially, the expressway is referred to as the Kan-Etsu Expressway Jōetsu Route. This designation consists of the entire Jōshin-etsu Expressway as well as the Kan-Etsu Expressway beyond Fujioka Junction to Nerima Interchange (concurrent with the Kan-Etsu Expressway Niigata Route).
 
The expressway begins at a junction with the Kan-Etsu Expressway in southern Gunma Prefecture and heads west, paralleling National Route 254 until Shimonita.  From here, the route branches north, passing Mount Myōgi, then heads west once more from Annaka.  The route parallels National Route 18 from this point until the terminus.
 
The expressway then follows a winding route through the mountainous area separating Gunma and Nagano Prefectures. From Saku, Nagano the route follows a northwesterly course, passing Mount Asama, until it reaches a junction with the Nagano Expressway near the city of Nagano.
 
The route heads north, following the east bank of the Chikuma River, before heading into the mountainous region separating Nagano and Niigata Prefectures.  The expressway continues north through Niigata Prefecture, passing Mount Myōkō, and eventually terminating at a junction with the Hokuriku Expressway in Jōetsu near the Japan Sea coastline.
 
It is in Niigata that one finds the village of Sekikawa – and the completion of one of the last parts of the route. 
 
The area of present-day Sekikawa was part of ancient Echigo Province, which during the Edo period, was mostly the purview of the Yonezawa Domain under the Tokugawa shogunate.  The area was organized as part of Iwafune District, Niigata following the Meiji restoration.   The modern village of Sekigawa was established in 1954 by the merger of the villages of Seki, Shichikatani, and Kukatani.  In modern times, its main occupation is agriculture.
 
On to the watch itself - Seiko introduced its 7Nxx movement in circa 1993, and it came in a range of styles and dial colors, to include the unique helmet-shaped watch here - Seiko would cease production of the calibre in 2009.
 
In 1969, Seiko released a first upon the world - the first quartz wristwatch, its Seiko Quartz Astron.  The Astron went on to change the way the world told time, and severely tested the dominance of the Swiss, bringing high technology within the reach of all.  The Swiss would literally pay for neglecting the evolution of the watch, in terms of market share and profit.
 
As the world got accustomed to the novel new Astron technology dominating the market in the late 1960s and early 1970s, Seiko was hard at work on its next innovation to challenge Swiss watch industry dominance, developing the Superior, Grand Quartz, King Quartz - and eventually the 7Nxx line here. 
 
Seiko launched its Avenue line in 1985, including its high-priced Chario and Société models.  The series was a hugely popular, thanks in part to the effect of TV commercials featuring popular artists.
 
In line with the watch style popular in the 1980s, a genre of watches referred to as "traditional watches" became popular.  Within the Seiko answer to this style - its Avenue line, like the watch here - was retro-inspired oxidized gold and silver exterior finishes featuring user-friendly dials either with 60 markers and classic numerals around the circumference or sans numerals. 
 
Avenue variations incorporated small second hand dials (like on the gold Avenue here) - and moon phase complications also proved popular with the line.
 
This gold Seiko dress watch comes on a black leather band, and with rugged travel case, Seiko 7Nxx instructions manual, and springbar tool.
