At its core, the link Seamaster Diver 300M is powered by the Omega link Co-Axial Master Chronometer Calibre link 8806. This METAS-certified movement guarantees accuracy between 0/+5 seconds per day while offering exceptional magnetic resistance up to 15,000 gauss. The Omega Seamaster Diver 300M in bronze gold is available from Omega (and fine Omega retailers) for $27,900 on the bracelet or $13,900 on a black rubber strap.

Notice that the drawing features two lug profiles with one hastily slashed out. There are scribbles and numbers possibly linking it to a record book a Cartier stamp in the lower left link corner and a signed "OK" in the top right likely pointing to final link approval of the project by Cartier's designers. All of link these tiny details are important considerations in understanding just how special and handmade these watches are.
