Seiko Grand Quartz 4842-5100 - HAQ Cal. 4842 - Textured Dial - 1977 JDM

This is the very definition of a "wolf in sheep's clothing" an elegant, unassuming gold-plated dress watch that houses one of the most precise, high-end quartz (HAQ) movements ever made. The Seiko Grand Quartz line was the flagship of Seiko's production in the late 1970s, positioned even above their best mechanical watches, and it was engineered with precision that remains world-class today.

The Story

The key collector detail is the movement: the Caliber 4842. This quartz engine was built by the Suwa Seikosha factory and was designed to be accurate to an incredible ±5 seconds per month! It achieves this through a high-frequency crystal and rigorous quality control. The ultimate sign of its prestige is the applied "twin quartz" logo on the dial two stylized tuning forks symbolizing the use of advanced quartz technology for stable timekeeping, a marker reserved exclusively for this elite series.

Aesthetically, the watch is a beautiful product of its time. The gold-plated case and the striking vertical linen-textured silver dial provide incredible depth and visual warmth. The case has a refined cushion shape, and the dial features a simple date window for clean, formal aesthetics. This Grand Quartz offers superior accuracy and unmatched vintage luxury a crucial piece of the Seiko story!

What You Should Know

  • Authenticity: Genuine product guaranteed.
  • Vintage Expectations: These are historic artifacts, often decades old. While we ensure they are running beautifully, a vintage movement cannot be expected to match the pinpoint accuracy of a modern contemporary watch. Original parts age naturally, and any servicing is meant to preserve the watch's mechanical soul, not return it to a factory-new state. This authentic, lived-in character is exactly what makes vintage horology so incredibly rewarding!
  • Customs & Import Duties: Import duties, taxes, and charges are not included in the item price or shipping cost. These charges are strictly the buyer's responsibility. Please check with your country's customs office to determine what these additional costs will be prior to purchasing.
  • Box/Papers: Aftermarket box provided. No original papers.
  • Water Resistance: As with all vintage watches, water resistance cannot be guaranteed. We strongly recommend avoiding contact with water.
