Today's offering showcases this impressive Certified Pre-Owned JLC Master Control Ultra Thin watch. The watch itself presents in 99% like new condition. Our photos couldn't do it justice!

For more than a century watchmakers have competed to showcase their top-tier watchmaking skill by crafting movements of shocking thinness. Most often they focused on handwound movements to avoid the challenges of fitting an automatic winding system into a small space.

But as time progressed gentleman wanted thin dress watches without sacrificing the convenience of automatic winding. Only a relatively few fine Swiss watchmakers have taken on the immense challenge of making an ultra thin automatic movement, because of the complexity and inherent reliability problems their mechanism would have to overcome.

To become of a part of Jaeger-LeCoultre's coveted Master Control series, watches are tested for 1000 hours in extreme conditions including categories of temperatures, shocks and vibrations, and must pass through magnetic fields of 5000 amperes per meter before being offered for sale.

To create an ultra thin automatic movement that met even this very high-standard is incredibly impressive, even at the top-tiers levels of watchmaking.

JLC created this classically elegant Master Control Ultra Thin watch to pay homage to the idea of the classic mens dress watch. Its sapphire glass exhibition case back showcasing its extremely fine ultra thin movement.

Its timeless silver dial has an "Explorer" style 3,6,9 configuration that truly harkens back to JLC's vintage heritage. Its business casual styled dial gives it much flexibility in pairing with a wide range of outfits.

The watch itself presents as 99% like new. The case has one tiny pin prick mark where the bezel meets the crystal. Otherwise it present as like new. The dial and crystal are both like new. The outside of the strap presents as just short of mint - the underside shows fairly light signs of use. A new strap would make the complete package gift quality.

Our Master Watchmaker has performed any needed servicing and replaced all of the waterproofing gaskets with new seals. It is keeping perfect chronometer grade time in all five testing positions.

For the finishing touch we have fully detailed it making it ready for immediate enjoyment.
