A narrow study in gold and proportion. This Seiko Lassale places a pale champagne dial inside a tall rectangular case, with fine baton markers and softly pointed hands keeping the face precise and quiet. The Lassale signature sits beneath twelve, while polished shoulders carry the eye directly into the bracelet.

The integrated bracelet is the defining gesture: broad stepped links, inset polished panels and a continuous gold-tone surface that feels closer to jewellery than conventional watchmaking. Slim, graphic and distinctly of its era, it brings a composed vintage finish to a bare wrist or a tailored sleeve.

  • Dial: Ivory white rectangular dial
    • Fine applied gold-tone baton markers on the 3, 6, and 9
    • Slender gold-tone hour and minute hands

Gentle Care & Handling

Watch Care Guide.

Gilded Hour Assurance

All watches are curated second hand timepieces, in confirmed working condition and sold as is. Long term accuracy cannot be guaranteed, but each watch is tested for at least 72 hours prior to dispatch.

All pieces leave our studio in running condition. Very rarely, a vintage movement may be affected during transit due to vibration or rough freight handling. This is an inherent characteristic of vintage timepieces and is outside our direct control.

Expect imperfections as description is made as accurate as possible but is not always 100% accurate. Be sure to check all photos.

We do not generally accept returns, or cancellations. But we will always strive to help you on a case by case basis. For more information, please head to our policy page.
