Vintage Seiko SQ Sports 150 Watch - Black Ceramic Coated & Gold - Thin Case - Screw Down Back - 1980s Quartz

The Artifact

In the late 1980s and early 1990s, the "black and gold" aesthetic was the ultimate signifier of executive cool. This vintage Seiko SQ Sports 150 captures that specific era perfectly.

Instead of traditional bare stainless steel, this piece features a sleek matte black ceramic coating across the case and integrated bracelet. This dark, stealthy profile is violently contrasted by brilliant gold-tone accents—on the bezel ring, the hour indices, the hands, the crown, and the articulated links of the bracelet. It is aggressive, refined, and distinctly retro.

The Design & Wearability

What makes this watch truly exceptional is its profile. Despite being a highly capable sports watch, it features an incredibly thin case design. It sits low and flat against the wrist, slipping easily under a shirt cuff. The integrated bracelet flows seamlessly from the case, making it wear more like a continuous, dark piece of armored jewelry than a standard timepiece.

The Machine

Don't let the thin, elegant profile fool you—this is a serious tool watch at its core.

• The Engine: Powered by a legendary Seiko Quartz movement, offering set-and-forget reliability alongside a highly legible day/date window at the 3 o'clock position.

• The Armor: As part of the "Sports 150" line, it was originally rated for 150 meters of water resistance. Crucially, it features a robust screw-down caseback to protect the movement from the elements, ensuring its longevity as an everyday field watch.

The Condition

Grade: Excellent Vintage.

• Case & Bracelet: The black ceramic coating is in remarkable condition, showing only very faint, honest micro-wear on the high edges, retaining its deep matte finish. The gold accents remain bright and unoxidized.

• Crystal: Clear and legible.

Why It Belongs Here

We love watches that master the art of contradiction. It is a rugged, 150M-rated sports watch with a screw-down back, but it is housed in a sleek, ultra-thin, ceramic-coated case that looks ready for a boardroom. It’s the ultimate 80s "power watch" executed with Japanese precision.
