Description from the seller
Brand: Seiko
Model: Seiko Kinetic SQ 50 Indicator "Starfish" Bezel
Reference number: 5M43-0A50
Movement: Hybrid mechanical-quartz / Kinetic.
Case material: Stainless steel and yellow gold-plated finishes. The case is distinguished by the iconic marine-inspired design, topped by a fixed or gold-plated rotating bezel with a sinuous profile and radially contoured waves. The case band houses at 3 o'clock a gold-plated knurled crown protected by shoulders, asymmetrically paired at 2 o'clock with a golden pump button to activate the instantaneous power-reserve indicator. The case back is screwed.
Dial color: White opaline. The sought-after technical and ergonomic layout features a red and gold power-reserve indicator arc printed in the upper section between 10 and 12 o'clock. The peripheral minute track is in black lines and is marked by geometric applied indices in a metallic gold tone with a facet cut. It has gold baton hands with partial LumiBrite luminescent fill, paired with a slim central second hand in gold. Under 12 o'clock is printed the SEIKO / KINETIC logo, while above 6 o'clock stands the applied SQ 50 emblem. A rectangular date window with a gold frame for the dual date is positioned at 3 o'clock.
Case diameter: Approximately 36 mm.
Crystal: Flat Sapphlex crystal.
Strap material: Original Seiko stainless steel bracelet with flat and articulated geometric link rows, enriched by two central parallel lines of links plated in bright yellow gold.
Strap color: Satin steel with bright yellow gold details.
Strap length: Approximately 20 cm.
Clasp: Fold-over deployant buckle with safety clasp.
Clasp material: Satin-finished stainless steel, customized on the exterior with the official SEIKO brand engraving.
