AI-assisted summary
Description from the seller
Brand: Omega
Model: Seamaster Cosmic Automatic Date.
Reference number: 166.026 - TOOL 107.
Movement: Automatic winding movement
Case material: Stainless steel plated in yellow gold with a glossy finish on the top and brushed sides. The case stands out for the avant-garde monobloc architecture free of a traditional removable caseback to ensure superior structural waterproofness. The silhouette is barrel-shaped with fluid lines, short integrated lugs, and a fixed sloping bezel. On the right side, the knurled winding crown bears the house logo and is partially set in. The case back shows circular satin finish and the famous Seahorse engraving, symbol of the Seamaster collection.
Dial color: Silvered dial with a refined sunburst finish. The dial presents a clean analog layout, surrounded around the edge by a black printed minute track with geometric divisions. It features applied faceted baton-style hour markers in yellow gold with a black central contrasting insert. In the center are coordinate baton-shaped hands in gold and black for hours and minutes, accompanied by a slender central seconds hand. At 3 o’clock there is a rectangular gold-framed date aperture with black numerals on a white background. Under the 12 o’clock index sits the raised brand logo accompanied by the printed inscriptions "Ω / OMEGA / AUTOMATIC", while the lower half reads the inscriptions "Seamaster / COSMIC" balanced on the edge by the seal "SWISS MADE".
Case diameter: approximately 35 mm
Crystal: Domed, highly transparent hesalite, shaped to hermetically couple with the monobloc case.
Strap material: Aftermarket leather with tonal edge stitching.
Strap color: Deep black with semi-gloss finish.
Strap length: progressively adjustable via central anchor holes.
Clasp: Traditional classic pin buckle.
Clasp material: Stainless steel plated in yellow gold with a glossy finish, consistent with the case’s gold tone.
Includes standard box, no warranty.
Shipping: Tracked and insured with DHL
Any duties are the buyer’s responsibility.
