Omega Planet Ocean 600m Co-Axial Master Chronometer GMT 43.5mm

Omega Seamaster Chronograph Automatic Mens Watch 215.33.44.22.01.001.  This watch features a brushed stainless steel case with polished beveled corners and a bezel crafted from stainless steel with polished black and white ceramic fill, distinguished by contrasting indices and numbers for clear night and day separation, plus a luminous dot at the starting point that emits green light. The high gloss black zirconium oxide ceramic dial has "[ZrO2]" engraved beneath the center hands and includes applied polished index hour markers and 6, 9, and 12-hour markers with luminous fill (blue emission), alongside a printed minute and seconds track. The polished facetted hands also have luminous fill—blue for the hour and seconds hands and green for the minute hand—and there is a date window at 3 o'clock and a helium escape valve at 10 o'clock. The GMT function is indicated by a spear-head hand with a luminous filled tip that completes a single rotation every 24 hours, pointing to the GMT timezone on the rotating bezel, designed to avoid confusion between day and night. Powered by the Omega Master Co-Axial caliber 8906, which beats at 25,200 vph and has 38 jewels and a power reserve of approximately 60 hours, this movement is METAS certified as a Master-Chronometer, ensuring water resistance, precision, and magnetic resistance up to 15,000 gauss. It features Omega's Si14 silicon balance spring for improved shock and magnetic resistance, along with the Co-Axial escapement for enhanced precision and durability, while the rotor and visible bridges showcase a unique "arabesque" wave design finish.
