Omega Seamaster, ref. CK 14390-3 SC (in stainless steel) The CK 14390, also known as the Pre-Seamaster 30, was introduced in 1958 and lasted until 1962. It is powered by an Omega caliber 285, a high-quality, extremely reliable movement based on the famous cal. 30 created in 1939. Its work-horse manual winding movement combined with its large case makes the CK 14390 a solid heavy-duty Seamaster.
