====== JLC 751 ====== The **JLC 751** and **JLC 752** are a family of [[double barrel]] [[chronograph]] watch movements from [[Jaeger-LeCoultre]]. Launched in [[2004]] for the new [[Jaeger-LeCoultre Master Chronograph]] and [[Jaeger-LeCoultre Master Compressor Extreme World Chronograph]], the JLC 751 and JLC 752 (respectively) were the first [[automatic]] [[chronograph]] movements ever produced by Jaeger-LeCoultre. It pioneered the vertical coupling system, allowing this [[column-wheel]] chronograph to be extremely precise. Calibres 751 and 752 are built into Jaeger-LeCoultre's [[Jaeger-LeCoultre Autotractor|Autotractor]] base, a modern and efficient platform. ===== Variants ===== The 751 is made up of 235 to 280 pieces (depending on variant), while the [[world timer]] 752 movement is made up of 279 pieces. Both run at 28,800 vph and list a power reserve of 65 hours thanks to a [[double barrel]] design. The JLC 752 shows hour, minute, and chronograph seconds coaxially, has a large date display, and a [[world timer]] dial around the peripheral. Subdials include a [[power reserve indicator]] and [[chronograph]] hour and 30-minute counters. All JLC 751 movements feature hour/minute/second hands, a small date window, and a chronograph with hour, 30-minute, and 60-second counters. Some feature an [[operating indicator]], which moves once per minute to show that the watch is operating. The JLC 751E in the AMVOX2 models also features a unique "vertical trigger", allowing the chronograph to be stopped and started by pressing the crystal. ^Movement^Winding^Pieces^Beat^Power Reserve^Jewels^Height (mm)^Notes^ ^751|[[Automatic]]|272|28,800|65 Hours|41|5.6|[[operating indicator]]| ^751A/1|Automatic|277|28,800|65 Hours|39|5.72| | ^751D|Automatic|272|28,800|65 Hours|41|5.65|[[operating indicator]]| ^751E|Automatic|280|28,800|65 Hours|41|5.65|[[operating indicator]] and vertical-trigger [[chronograph]]| ^751F|Automatic|277|28,800|65 Hours|39|5.72| | ^751G|Automatic|235|28,800|65 Hours|37|5.72| | ^752|Automatic|279|28,800|65 Hours|41|5.6|[[world timer]]| ^752/1|Automatic|279|28,800|65 Hours|39|5.72|[[world timer]]| ===== Applications ===== Jaeger-LeCoultre currently uses this calibre and its variants in a large number of watches, making it the company's most-common current chronograph movement. * [[Jaeger-LeCoultre Master Compressor Chronograph]] (JLC 751) * [[Jaeger-LeCoultre Master Chronograph]] (JLC 751A/1) * [[Jaeger-LeCoultre Master Compressor Diving Chronograph]] (JLC 751D) * [[Jaeger-LeCoultre Master Compressor Diving Chronograph Lady]] (JLC 751D) * [[Jaeger-LeCoultre AMVOX2 Grand Chronograph]] (JLC 751E) * [[Jaeger-LeCoultre AMVOX2 DBS Transponder]] (JLC 751E) * [[Jaeger-LeCoultre AMVOX2 Rapide Transponder]] (JLC 751E) * [[Jaeger-LeCoultre AMVOX2 DB9 Transponder]] (JLC 751E) * [[Jaeger-LeCoultre Master Compressor Chronograph 2]] (JLC 751F) * [[Jaeger-LeCoultre Deep Sea Vintage Chronograph]] (JLC 751G) * [[Jaeger-LeCoultre Master Compressor Extreme World Chronograph]] (JLC 752) * [[Jaeger-LeCoultre AMVOX5 World Chronograph]] (JLC 752) * [[Jaeger-LeCoultre AMVOX5 World Chronograph Racing]] (JLC 752) * [[Jaeger-LeCoultre AMVOX5 World Chronograph Cermet]] (JLC 752/1) ===== External links ===== * [[http://www.qpmagazine.com/media/39293/Shock_Tactics_Jaeger_LeCoultre.pdf|Shock Tactics]] **Manufacturer:** * [[Jaeger-LeCoultre]] **Description:** * [[Automatic]] movement **Functions:** * Hour/minute/second hands * Small date window * Chronograph with hour, 30-minute, and 60-second counters * [[World timer]] * [[operating indicator]] * "Vertical" chronograph trigger on the crystal **Data:** * H 5.60, 5.65, or 5.72 mm * 37, 39, or 41 [[jewels]] * 28800 A/h * Power reserve 65 hours **Production period:** * [[2004]]-present {{tag>Movements Double_barrel_movements Automatic_movements Automatic_chronograph_movements Worldtimer_movements Chronograph_movements Jaeger-LeCoultre_calibres Jaeger-LeCoultre_Autotractor_calibres Column_wheel_chronograph_movements}}
