Description
This 1999 Omega Seamaster is a prime example of the combination of highly functional diving technology and sophisticated design. As one of the most defining iterations of the Diver series, this reference represents the era in which Omega redefined the aesthetics of the modern sports watch.
The high-quality stainless steel case has a diameter of 41 mm and features the characteristic curved lugs (“Lyre Lugs”). The dial stands out with its classic, galvanic blue wave pattern, which creates visual depth and underscores the watch’s maritime heritage. The skeletonized hands and applied indices are generously coated with tritium or early Super-LumiNova, ensuring excellent legibility in all lighting conditions.
This watch is powered by the Omega Caliber 1120. This automatic movement is known for its slim construction and exceptional reliability. Based on an enhanced architecture, it is certified as a chronometer (COSC) and offers a power reserve of approximately 44 hours. Thanks to its precise regulation, this movement is considered by watchmakers to be one of the most stable calibers of its generation.
The Seamaster is designed as a professional instrument for diving:
Water resistance: Up to 300 meters (30 bar).
Helium escape valve: Prominently positioned at 10 o’clock to allow pressure equalization during professional dives.
Bezel: Unidirectional rotating with a blue Aluminium insert for reliably measuring dive time.
Crystal: A scratch-resistant, domed Sapphire Crystal with inner anti-reflective coating protects the watch’s iconic face.
The five-link stainless steel bracelet, with its elaborate brushing and polishing, is considered one of the most comfortable bracelets in the watch world. The solid safety folding clasp features an integrated diving extension, allowing the watch to be worn easily over a wetsuit.
This 1999 reference 2531.80.00 is a timeless classic that perfectly combines technical excellence and sporty elegance.
