Serviced and guaranteed quartz chronograph with new crystal and strap. Model History: Introduced in 1983, the Seiko 7A28 series represents a milestone in watchmaking as the world’s first analog quartz chronograph. Unlike later mass-produced quartz movements, the 7A28 was fully metal-constructed, jeweled, and engineered for long-term serviceability. The reference 7A28-7040 is among the most recognisable versions, often referred to by collectors as the “Seiko Speedmaster” due to its balanced chronograph layout, tachymeter bezel, and professional tool-watch design. This example dates to April 1983, placing it in the early production period of this historically important model.
