The Omega Seamaster 2804.30.37 is a very special model in the Seamaster Aqua Terra Mid-Size collection. The defining feature of the Omega Seamaster 2804.30.37 Aqua Terra 2500 series is the Omega Caliber 2500. This is an automatic movement equipped with a Co-Axial escapement. The Caliber 2500 is Chronometer certified by the COSC (Control Officiel Suisse des Chronomètres). This means that each movement has undergone rigorous precision tests and has received a certificate from this official Swiss organization. So when you see "Omega Aqua Terra 2500" you can be sure that these watches are chronometer rated and guarantee a high level of accuracy. The product you are reviewing was produced in 2002 and is one of the first Caliber 2500s. When I purchased it, it came with a slightly worn box and an Omega user manual. This is how I will send it to its new owner.
Professionally restored and FULLY SERVICED (movement completely disassembled, all parts cleaned, oiled and adjusted to their taste) your watch will work without any unpleasant surprises. (No service needed for 3 years unless exposed to adverse conditions such as water impact and high humidity.)
