Just be­low the high­est point of the domed dial crys­tal, the bal­ance of LM SE beats at a se­date, tra­di­tional 2.5Hz / 18,000bph. What is rather less tra­di­tional is its con­struc­tion. Un­like most of the other sus­pended bal­ances in the Le­gacy Ma­chine col­lec­tion the bal­ance of LM Split Es­cape­ment seems to os­cil­late on its own, without any vis­i­ble in­take of en­ergy. The es­sen­tial re­main­ing parts of the es­cape­ment, which pro­vide the driv­ing im­pulse – an­chor and es­cape wheel – are con­cealed on the op­po­site side of the move­ment, al­most 12mm be­low; hence the name ‘Split Es­cape­ment’. Un­der the bal­ance, the triple-dial de­sign of LM SE gives the time at 12 o’clock, the power re­serve in­di­ca­tion at 4 o’clock and the date at 8 o’clock. The date can be quickly and eas­ily ad­justed thanks to a push-but­ton on the side of the case, next to the date dial.
