Longines Grand Classic L4.721.2 – Watch Service | Caliber L619 (ETA 2892-A2)

In this video, I take you through the servicing of a Longines Grand Classic L4.721.2, powered by the Longines L619 automatic movement, based on the renowned Swiss ETA 2892-A2 caliber. The background music comes from a recent live jazz concert of ours, recorded casually using nothing more than an iPhone's built-in voice recorder. The keyboard player is a good friend of mine — and also the proud owner of the very watch featured in this video!
