While we usually see Omega on the sporty side of things, with complications that range from the date to the annual calendar or the chronograph – except that one central tourbillon watch – complicated watches are not really part of the Biel-based brand. This was until 2017, when Omega introduced, as an exclusive limited edition in platinum, a Worldtimer version of the Seamaster Aqua Terra. This complex watch now comes back in regular production, with multiple editions in steel or in Sedna gold.
