Jaeger-LeCoultre Extreme Lab 2 New Movement Specs

Key Points from the Discussion

• The movement replacement is likely due to an upgrade designed to reduce wear issues, specifically involving pivots and jewels. New wheels with larger pivots require new jewels, which may not fit older bridges, making a full bridge or movement swap necessary for improved reliability.
• The author ultimately chose to proceed with the upgraded movement, prioritizing long-term serviceability by JLC and wearability over potential secondary market value impact, especially since the replacement cost was equivalent to a standard service.
• While the new movement offers an 'effectively new and better watch,' there's a consensus that such a significant alteration could negatively impact the watch's value in the secondary market, a common concern for JLC models.
• Some collectors express strong preference for the original black-bridged movement, finding the lighter version less appealing and questioning the necessity of a full movement change for issues like running fast.
• There is a general expectation that luxury brands should be capable of repairing their products without requiring full movement replacements, especially for watches that are only 13 years old, raising questions about JLC's service policy transparency.
• The lighter movement does offer improved visibility of the intricate mechanics, which can be an aesthetic advantage for some collectors, despite the preference for originality.
