Seiko 7139-7060
This one is known as the “Sunrise.” From November 1972. Looks like it could have been manufactured yesterday!
Some specs:
The Seiko "Sunrise" is a 1970s Japanese domestic market (JDM) automatic chronograph, often featuring a vibrant teal-to-yellow gradient dial. Key specs include a 40mm stainless steel case, Seiko Caliber 6139B movement, an internal rotating countdown bezel, and a 30-minute chronograph register.
Key Specifications & Features
- Movement: Seiko Caliber 6139 (automatic, 17 or 21 jewels), vertical clutch, column wheel.
- Case Dimensions: 40 mm diameter
- Case Material: Stainless steel with a cushion/helmet-style shape.
- Dial: sunburst "sunrise" dial with yellow/orange accents, often with "Speedtimer" text.

Unique "Sunrise" Characteristics
- Dial & Hands: The "sunrise" nickname refers to the dial's gradient effect. It features distinctive white/black hands and an orange chronograph sweep hand.
- Sub-dial: The 30-minute sub-dial at 6 o'clock often has partial black paint, leaving a segment for a specific "sunrise" effect.
- Crown & Pushers: has a distinct, often partially shrouded crown, making it harder to grip than other 6139 models.
- JDM Exclusivity: As a Speedtimer, it was specifically meant for the Japanese Domestic Market.
