Doxa Conquistador, Ref. 684415, Cal. ETA 2651, Women’s, 1974
A blue date wheel adds a small color accent to this 1974 Doxa Conquistador by Synchron. Its silver sunburst dial sits inside a dark oval frame, surrounded by a polished stainless-steel cushion case. The 28 mm women’s watch uses the ETA 2651 automatic caliber and is fitted with a new textured black leather strap.
Silver Sunburst with a Blue Date Wheel
The radial silver finish reflects light beneath applied baton markers with dark central inserts and polished edges. DOXA by SYNCHRON appears below 12, with conquistador and AUTOMATIC above 6. A framed date aperture at 3 o’clock displays the blue date wheel.
Slim baton hour and minute hands have dark central inserts matching the markers and inner frame. A fine central seconds hand completes the display. Visible aging remains around the outer dial and crystal perimeter.
Polished Cushion Case
The stainless-steel case has rounded sides and broad polished surfaces around the dark oval inner bezel. It measures 28 mm across and 30 mm lug to lug, with a 12 mm strap connection. The shaped opening makes the dark frame a prominent part of the compact watch’s appearance.
Light surface wear remains visible, while the case presents cleanly overall. The back carries the by Synchron emblem. A signed fluted crown at 3 o’clock provides a grip for setting without interrupting the rounded case outline.
ETA 2651 and the Synchron Identity
The Swiss ETA 2651 automatic movement supplies self-winding power to the central time display and date. The DOXA by SYNCHRON dial signature and matching caseback emblem preserve this Conquistador’s Synchron-era identity.
New Grained Leather Strap
The new high-quality black leather strap has a textured grain, light underside and classic pin buckle. Its 12 mm width follows the compact lugs, and its dark finish continues the contrast around the dial. The strap is a replacement, separate from the original watch components.
The watch is fully serviced and fully operational, retaining its original watch components. A 12-month warranty is included, with no box or papers. Worldwide shipping is available.
