Vintage Seiko 7N43-9080 Quartz Day-Date Black Dial Luminous Bar indexes 3 hands Analogue Metal Band New Battery Excellent Condition: KQ220 The Seiko 7N43-9080 is part of the late-1990s to early-2000s generation of affordable Japanese domestic-market (JDM) Seiko quartz watches. Models using the 7N43 movement were commonly sold under the “Spirit” line in Japan, positioned as reliable everyday business watches with clean styling, strong accuracy, and extremely low maintenance. The marking “1 JEWEL 7N43C” is very interesting because it identifies a later and slightly upgraded variant of the standard Seiko 7N43 family. The black dial version with fluorescent bar indexes represents the classic minimalist Seiko office-watch design language of that era. Near the end of the 1990s, Seiko was refining its post-quartz-crisis philosophy by A) making quartz movements extremely durable, B) simplifying servicing C)improving battery life and D) keeping dimensions slim and wearable in short offer “daily practical luxury” rather than flashy design. Experience understated Japanese elegance with this Seiko 7N43-9080 quartz watch. This model is equipped with the Caliber 7N43, a well-known Seiko quartz movement appreciated for its long-term reliability, stable accuracy, and low maintenance requirements. The minimalist three-hand configuration and sharp bar indexes reflect the line’s focus on clarity and functionality. The watch features a clean silver round bezel case with a balanced, versatile design suitable for both business and casual wear. The silver bezel round case, combined with luminous stylish bar indexes and three-hands dial, creates a sophisticated and timeless appearance. Designed for precision and everyday reliability, this model uses Seiko’s trusted 7N43 quartz movement, known for its accuracy and longevity. The battery has been replaced May 7th, 2026, and the watch is in excellent condition, ready to wear immediately. The Seiko Caliber 7N43 is a highly reliable Seiko analog quartz movement designed for long service intervals and low power consumption. Historical Importance of the 7N Series sits historically between older 1980s Seiko quartz movements and later high efficiency 7N/6G/8J generations. It represents Seiko’s transition toward low-cost mass reliability, minimal servicing and thin everyday quartz watches. This is one reason many 7N watches still run accurately after 25–30 years. Reliability Reputation among collectors and repairers, the 7N43 is considered one of Seiko’s most dependable simple quartz movements, easier to maintain than many Swiss quartz calibers cheaper to replace than repair and capable of decades of service. A refined and dependable watch that reflects Seiko’s commitment to quality and timeless design. Features: ■Brand: SEIKO ■Model Number: 7N43-9080 ■Product Number:220877: February 2002 Seiko serial numbers are six digits long, with the first two digits indicating the year and month of manufacture. The first number （2） indicates the second year of the 2000s, meaning the watch was manufactured in 2002. The next letter （2） is the month code. For Seiko, 1-9 represents January through September, O = October, N = November, and D = December. → "N" is November. Therefore, this watch was manufactured in February 2002 ■Accessories: Body only ■ Technical features of the 7N43Cmovement: • Movement: Quartz (Battery-Powered) caliber 7N43C is an analog quartz watch movement. Production started around 1993, and production finished in 2009. • Battery:SR920SW /371（Silver oxide) New battery was replaced May 7th, 2026 • Accuracy:±15 seconds/month • Day / date: Day + date • Frequency: Standard 32,768 Hz quartz crystal oscillator （typical for Seiko analog quartz）. While the exact ± rating for 9539 isn’t published, many similar quartz movements from Seiko of the era were around ±20 seconds/year accuracy. • Number of jewels: 1 Usually 0 jewels Seiko 7Nxx family use no jewels, since pure quartz stepping motor movements don’t need them. • Size / diameter:23.5mm x 21.9mm X Height:2.9mm • Development division: Suwa Seikosha (Nagano) and Tokyo’s Kameido factories were primary quartz production hubs for Seiko at this time, producing reliable analog quartz engines • Notes: The same as cal. 7N42 but with a day display （as well as date）. There are 7N43A and 7N43C variants of this movement –7N43Cis about 0.1mm thinner and has one jewel, whereas 7N43A has no jewels. PDF guides: Instruction manual （English） • Maintenance: Battery replacement allows for extended use, but as this is an older model, care should be taken to prevent deterioration of the electronic components. This movement is widely used as Seiko's popular quartz movement and is characterized by its good balance of reliability and ease of maintenance. ■Materials: • Case: Stainless Steel • Case Size:37mm excluding crown X 44mm including case lug Thickness: 9mm • Dial: Silver Bezel case and rich pitch-black dial with luminous stylish bar indexes and three-hands dial display combined for both legibility and elegance • Secondhand Stop Function: Yes （second hand stops when setting the time） • Weight:100.7gms • Water Resistant : resistant for everyday life water dishing/showering but don't expect too much from it: Even if it was labeled "Water Resistant" at the time, it doesn't meet modern Water-Resistant standards. Avoid using it around water. • Class 1 antimagnetic watch: Anti Magnetic 60G This watch meets the standard of being able to maintain its performance in most cases even when brought up to 5cm from devices that generate magnetic fields in everyday life （ability to withstand a DC magnetic field of 4800 A/m）. • Crystal: sapphire crystal • Band: Silver Stainless-Steel band with 19cm circumference wrist length measured by tape ■Guide to set day/date/time: • Pull the notch out second position to rotate to change for correct hour minute and second • Pull the notch out first position to turn clockwise for a change of weekday then turn counterclockwise for a change of Date. ■Condition: Overall: The watch is in good pre-owned vintage condition and is currently in working order. There are light scratches and signs of wear on the case consistent with normal use over time.

The crystal shows some minor micro-wear upon close inspection. New Battery replaced May 7th,2026, of this year, and it was functioning normally at the time of listing, so it should continue to function without any issues. Please be sure you are satisfied with the condition before bidding, so please check the photos and product description and ask any questions you may have (please note, however, that we may not be able to answer questions close to the end of the auction) ■Additional Note for caliver 7N43C: The marking “1 JEWEL 7N43C” is very interesting because it identifies a later and slightly upgraded variant of the standard Seiko 7N43 family. The “1 JEWEL” marking means Seiko added a synthetic ruby jewel bearing at a critical high friction point inside the movement. In quartz movements, jewels are not mainly about prestige like mechanical watches. Instead, they reduce friction/wear/power consumption/long-term gear/play deterioration. In the 7N43C, the jewel is usually installed around: the step motor rotor shaft or a critical wheel pivot in the train This helps smoother stepping/lower battery drain/improved long-term durability
