Seiko - 1977 Automatic Chronograph 'Baby Jumbo' 6139-7070 Black

WHAT WE LOVE:

A sleeper hit from Seiko’s golden era of mechanical chronographs, the 6139-7070 — nicknamed the “Baby Jumbo” — offers bold 1970s styling with a strong wrist presence. The black dial features a sub-dial at 6 o'clock and an outer tachymeter scale, with day-date display framed at 3 o’clock. The case’s tonneau-style silhouette, along with recessed pushers and a subtle sunburst brushing, makes this a standout among Seiko’s vintage chronos.

WHAT’S INSIDE:

Inside ticks the Seiko Caliber 6139, one of the world’s first automatic chronograph movements. It features a 30-minute chronograph counter, day-date complication with quickset, and operates at 21,600vph.
