The 35mm case is classic in its proportions, with a simple, rounded silhouette, thin polished lugs, and a smooth, flat bezel that draws comparisons to Patek Philippe's Calatrava style — a notable departure from the bolder, more angular \"C-shaped\" Constellation cases of the same era.\u003c\/p\u003e\n\u003cp\u003eThe stainless steel case features a screw-down back engraved with the Constellation insignia, and houses Omega's Calibre 1250, an electronic tuning fork movement offering Chronometer-certified precision, a traditional quick-set date display at 3 o'clock that can be set in either direction, and an audible 300Hz hum in place of a conventional tick — a genuinely unusual sensory experience that sets the f300 family apart from any mechanical or quartz watch.\u003c\/p\u003e\n\u003cp\u003e Designed by Max Hetzel, formerly of Bulova, and produced under licence from Bulova as the \"Omega f300,\" this calibre represents a significant chapter in the history of electronic horology. The dial presents with applied baton hour markers and slim, legible hands in keeping with the watch's understated, refined character. This example presents in excellent condition.\u003c\/p\u003e\n\u003ch3 class=\"page-heading-title ng-binding\"\u003eSpecifications:\u003c\/h3\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 26px;\"\u003e\n\u003ctd style=\"height: 26px;\" width=\"50%\"\u003e\u003cstrong\u003e\u003cbig\u003eMovement\u003c\/big\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"height: 26px;\" width=\"50%\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 21px;\"\u003e\n\u003ctd style=\"height: 21px;\"\u003eType\u003c\/td\u003e\n\u003ctd style=\"height: 21px;\"\u003e\u003cspan\u003eElectronic Tuning Fork\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 21px;\"\u003e\n\u003ctd style=\"height: 21px;\"\u003e\u003cspan\u003eCalibre\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"height: 21px;\"\u003e\u003cspan\u003eOmega Cal. 1250\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 24px;\"\u003e\n\u003ctd style=\"height: 24px;\"\u003eFunctions\u003c\/td\u003e\n\u003ctd style=\"height: 24px;\"\u003e\u003cspan\u003eHours, Minutes, Sweep Seconds, Date (Quick Set, bi-directional)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 21px;\"\u003e\n\u003ctd style=\"height: 21px;\"\u003eFrequency\u003c\/td\u003e\n\u003ctd style=\"height: 21px;\"\u003e\u003cspan\u003e300 Hz\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 21px;\"\u003e\n\u003ctd style=\"height: 21px;\"\u003eJewels\u003c\/td\u003e\n\u003ctd style=\"height: 21px;\"\u003e\u003cspan\u003e12\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 21px;\"\u003e\n\u003ctd style=\"height: 21px;\"\u003eCertification\u003c\/td\u003e\n\u003ctd style=\"height: 21px;\"\u003e\u003cspan\u003eChronometer\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 26px;\"\u003e\n\u003ctd style=\"height: 26px;\" width=\"50%\"\u003e\u003cstrong\u003e\u003cbig\u003eCase\u003c\/big\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"height: 26px;\" width=\"50%\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 44px;\"\u003e\n\u003ctd style=\"height: 44px;\"\u003eCase Material\u003c\/td\u003e\n\u003ctd style=\"height: 44px;\"\u003eStainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 22px;\"\u003e\n\u003ctd style=\"height: 22px;\"\u003eCase Diameter\u003c\/td\u003e\n\u003ctd style=\"height: 22px;\"\u003e35.0 mm (excluding crown)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 22px;\"\u003e\n\u003ctd style=\"height: 22px;\"\u003eCase Back\u003c\/td\u003e\n\u003ctd style=\"height: 22px;\"\u003eScrew-down, engraved with Constellation insignia\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 44px;\"\u003e\n\u003ctd style=\"height: 44px;\"\u003e\u003cspan\u003eCrystal\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"height: 44px;\"\u003e\u003cspan\u003eAcrylic \/ Plexiglass\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 22px;\"\u003e\n\u003ctd style=\"height: 22px;\"\u003e\n\u003cp\u003e\u003cspan\u003eDial\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"height: 22px;\"\u003e\n\u003cp\u003e\u003cspan\u003eOriginal Omega factory dial with applied baton hour markers and luminous hands\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"50%\"\u003e\u003cb\u003eStrap\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd width=\"50%\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eStrap Material\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eVintage leather;
