Debuting in late 2018, this Omega Constellation Manhattan Co-Axial Master Chronometer features a 29mm stainless steel and 18K Sedna gold case with a diamond bezel. Its brown dial is set with diamond markers and includes a date window at 6 o'clock, alongside hour, minute, and second functions. The timepiece is powered by the METAS-certified self-winding calibre 8700, which provides a 50-hour power reserve and 15,000 gauss magnetic resistance, visible through the transparent case back, and is mounted on a steel and 18K Sedna gold bracelet.
