Seiko introduced the Calibre 66 series – like this just serviced 66-7100 variant here from 1972 – in the mid-1960s as a no-nonsense minimalist dress watch, hand wound, and without date.
Seiko specialized in clean dials, not marred by any date function or numerals, in the 1950s and 1960s, coupled with thoughtfully chose dial fonts to present pure class – and this dial is no different. Complementing this is an unpolished case, with crisp angles and sharp corners, and dauphine hands.
One of the major draws of Seiko’s automatic dress watch line were their amazingly simplistic dials. All these singular features combine to form its single greatest aesthetic quality, namely, symmetry. The subtlety raised hour indices coupled with the sparse dial give this 66-7100 a simple, clean symmetrical style hard to find in a watch of any era or price range – everything is in balance.
This 66-7100 comes with a leather strap, nylon NATO strap, springbar tool, and Pelican travel case.
