Omega 2393 Chronograph 18k 1960

Omega Chronograph Ref. 2393 – Jumbo Yellow Gold Cal. 33.3 CHRO (1960) A very rare find from the golden era of Omega chronographs — this Omega Ref. 2393 from 1960 combines a large 37.5 mm 18k yellow gold case with one of the manufacture’s most historically important chronograph movements. Inside beats the Omega Cal. 33.3 CHRO T5-170, a highly regarded manual-winding chronograph caliber known for its precision, durability, and elegant construction. Developed in the 1930s, this movement family is especially admired by collectors as an important predecessor to the legendary Omega Cal. 321, later made famous by the Speedmaster and Moonwatch history. The watch itself offers exceptional wrist presence thanks to its jumbo yellow gold case, long lugs, and beautifully balanced proportions. The original silver dial remains in good condition, showing only a light and even patina that adds warmth and authenticity without disturbing the overall elegance. Golden hands and hour markers complete the refined look, giving the chronograph a classic and highly sophisticated appearance. Preserved in excellent overall condition and accompanied by an Extract from the Archives of Omega, this is a rare opportunity to acquire one of Omega’s most important vintage chronograph references. A collector-grade Omega chronograph — combining historical movement significance, precious metal presence, and timeless 1960s elegance. - wrist size in our picture is 18cm circumference - DIAL: original never touched silver colored dial in good condition original hands & crown some slight patina throughout the dial STRAP & BUCKLE: brown KARDINAL Lizard Embossed Leather Watch Strap fitting up to 20 cm wrist size / 3.7 mm thick gold plated GOLDAMMER buckle CASE: excellent overall condition, showing very minor traces of use 3- body 18k yellow gold case with snap-on case back 37.5 mm (without crown) / 46 mm (lug-to-lug) / 20 mm (between lugs) / 12 mm thick Year: 1960 reference: 2393 total weight: 52 g MOVEMENT: Omega Caliber 33.3 CHRO T5 - 170 - manual 17 jewels, 18000 A/h, 44 hours power reserve professionally serviced 05/2026 -4 sec/d / 280° BOX & PAPERS: comes with Extract from the archives of Omega (issued January 2021) GOLDAMMER certificate of authenticity & service documentation card GOLDAMMER REFERENCE: #1492
