Jaeger-LeCoultre Caliber 219 – Technical Overview from Document 1088_JLC

The Jaeger-LeCoultre Caliber 219 is a well-regarded manual-winding mechanical movement, serving as a close successor to Caliber 218 and employed extensively in mid-20th-century wristwatches. Document 1088_JLC provides a detailed technical overview, focusing on the movement’s construction, key features, and recommended servicing procedures.

Technical Specifications

• Type: Manual-winding

• Functions: Hours, minutes, small seconds

• Jewels: Typically 17

• Frequency: 18,000 vibrations per hour (2.5 Hz)

• Power Reserve: Approximately 40 hours

• Diameter: Approximately 27.0 mm

• Height: Approximately 3.5 mm

The Caliber 219 maintains a slim profile and is recognized for its precision and reliability in elegant timepieces.

Movement Architecture and Features

According to document 1088_JLC, Caliber 219 incorporates:

• Small seconds subdial at 6 o’clock, driven by the fourth wheel

• Two-bridge design, enhancing structural stability and facilitating easier servicing

• Efficient gear train and mainspring barrel for consistent energy transmission

• Shock protection system on the balance staff, usually Incabloc

• Smooth manual winding and setting mechanism, designed for durability and ease of use

This movement offers a harmonious balance between mechanical sophistication and practical functionality.

Servicing Notes

• Lubrication: Apply synthetic oils at escapement pivots, balance jewels, and gear train bearings; grease the barrel arbor and winding components sparingly

• Regulation: Target amplitude of 250°–280° with a beat error below 0.8 ms for optimal timekeeping accuracy

• Small seconds function: Check for secure seating and smooth rotation of the fourth wheel pinion and seconds hand

• Keyless works: Regularly inspect for wear on the setting lever spring, yoke, and sliding pinion to maintain smooth operation

Applications

Caliber 219 was typically used in:

• Mid-century Jaeger-LeCoultre dress watches requiring reliable manual-wind calibers with small seconds

• Timepieces crafted in stainless steel or precious metals, with case sizes generally around 34–36 mm

• Watches favored by collectors for their classic design and mechanical resilience

Conclusion

The Jaeger-LeCoultre Caliber 219, as outlined in document 1088_JLC, represents a refined manual-winding movement combining traditional craftsmanship with precise engineering. Its design prioritizes both performance and ease of maintenance, making it a popular choice in vintage JLC collections. The caliber remains appreciated for its reliability, elegant simplicity, and the hallmark quality of Jaeger-LeCoultre watchmaking.
