One of the major draws of Seiko’s 6619 automatic line - like the fully serviced 1967 Seiko 6619-8060 MACV-SOG Arabic dial automatic sport diver here, with vintage Waltham military compass, NOS USMIL strap, and MACV-SOG patch - were their amazingly simplistic dials and hands. These combine to form its single greatest aesthetic quality – symmetry. But what else is significant about this Seiko 6619...
Ah yes – this is one of at least four Seiko divers procured by the U.S. Military Assistance Command Viet Nam – Studies and Observations Group (MACV-SOG) and issued to U.S. Special Forces during the conflict. During the era these were made, Arabic numeral dial designs were rare and quite the departure from the norm. It’s a safe assessment the Arabic numerals were one of the aspects MACV-SOG favored, and USMIL forces assigned to the secretive group were either issued these watches or instructed to purchase them at the PX before a covert ops tour.
A highly classified multi-service USMIL Special Operations unit, MACV-SOG conducted covert unconventional warfare operations prior to and during the Viet Nam War. The unit conducted cross-border operations from Viet Nam into neighboring Laos, Cambodia, and North Viet Nam, with the USG infamously denying its existence until declassified in 1997. SOG operations levied a high toll on North Vietnamese logistic supply lines and bases in Laos and Cambodia following the early 1968 Viet Cong Tet Offensive.
But to operate in a non-attributable manner in these countries – where the USMIL wasn’t supposed to be – required atypical equipment. Established in 1963 and principally run by Conrad “Ben” Baker, the USMIL's Okinawa, Japan-based Counter Insurgency Support Office’s (CISO) main mission was to issue standard and untraceable (read, sterile in appearance to offer a fig leaf of plausible deniability when USMIL forces were operating somewhere they weren’t supposed to be in the countries in and around Viet Nam) gear, clothing, and weapons to Special Forces in Vietnam, to include the USMIL’s MACV-SOG. It would cease operation in 1973, following the US withdrawal.
The story of CISO and Ben Baker, these Seiko watches, and the work of SOG operatives is told by Frank Greco in his book, “Running Recon: A Photo Journey with SOG Special Ops Along the Ho Chi Minh Trail.” The Seiko 5's ordered by Ben Baker have become much sought after in vintage military and Seiko collecting communities.

Per Greco’s tome and our additional in-depth research, SOG forces used four different Seiko references. Some were CISO-issued beginning in circa 1968 and some preceded this time (so-called “Pre-CISO” watches) – the 6619, 6119-8100, 7005-8030, and the 6106-8100. Of the four, the first iteration were the 6619 models, made available in two sequential styles, the 8280 and then the 8060. The 6119-8100 would subsequently replace the 6619, and be followed by the 7005-8030.
This Seiko 6619 MACV-SOG comes on a NOS USMIL nylon strap, and with premium OD green nylon strap, springbar tool, SOG patch, vintage Waltham compass, and rugged travel case.
MACV-SOG 1967 Seiko 6619-8060 Automatic, w/Waltham Military Compass
DIAL: Brilliant steel-gray sunburst Arabic dial - note blemish at two o'clock position. Each hour indice is marked with a lumed Arabic numeral; matching baton hands and chapter ring is sans minute marks. Day and date function at 3 o'clock position- with the quite atypical color contrast between the two - works as designed.
CASE: Stainless-steel case measures 36.5mm x 43mm, with matching snap caseback - all inscriptions are legible and crisp.
CRYSTAL: Domed acrylic crystal, no deep scratches or cracks.
BAND: This 6619 comes with a dark green new-old stock nylon USMIL strap, which features matte grey hardware - note the USMIL nylon strap is slightly smaller than the watch lugs by design, as it was when issued to fit the Waltham compass; this Seiko also comes with a new OD green premium nylon strap. Both compliment the military look and heritage of this MACV-SOG Seiko.
MOVEMENT: 17-jewel Seiko 6619 automatic movement, manufactured August 1967, which beats at 18,000 bph. We have performed a full service on this MACV-SOG Seiko.
CROWN: Unsigned stainless-steel crown, mostly recessed.
This Seiko 6619 comes with a working vintage matte green Waltham military compass, akin to those used by MACV-SOG and other NATO military partner forces during the era.
A portion of the sales from all of our vintage MACV-SOG Seiko watches are donated to the Special Operations Association and the Third Option Foundation. The SOA benifits a range of programs for the USMIL Special Operations Community from scholarships to POW/MIA efforts; the Third Option provides support to surviving family of CIA Special Activities Center (SAC) operators and offers medical services for active-duty operators.
