Rather than the familiar pie-pan, it carries the rail track dial - the verticaly brushed central section framed by a railroad-style minute track and gold dial furniture. It is the underdog of the pie-pan, no less desirable and in fact rarer to find. \u003c\/p\u003e\n\u003cp dir=\"ltr\" class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cmeta charset=\"utf-8\"\u003eThe 34.5mm stainless steel case has the model's downturned lugs, topped by an Omega-signed crystal, with the case maker's \"CB\" mark for Central Boîtes present inside. The caseback carries the well known gold observatory medallion, the mark of the Constellation's chronometer heritage. Inside is the automatic chronometer-certified Caliber 561, the workhorse that earned the line its reputation for precision, here with sweep seconds and date.
