Explore mj23's macro photography of a watch pallet jewel. Discuss potential movement damage, lubrication issues, and expert insights on watch maintenance.

In a captivating post, mj23 shares an ultra-high-magnification photograph of a pallet jewel, inviting the community to examine intricate details often unseen by the naked eye. This close-up view sparks a crucial discussion among collectors about potential issues like material integrity and lubrication within a watch movement. mj23's image serves as a valuable reference point for understanding the microscopic world of horology.

Key Points from the Discussion

The primary concern raised by the image is whether the visible 'chips' are manufacturing defects or if the pallet jewel itself has caused damage, potentially leaving debris within the movement.
The presence of corundum particles (from a chipped jewel) within the movement could lead to catastrophic abrasion, especially if they mix with lubricating oils and affect critical pivots.
An alternative interpretation suggests that the visible anomalies on the escape wheel teeth might be migrating pallet oil rather than actual material chips.

I have seen Mila Kunis in the nude in person and the movement is much more pleasing to look at. Jus’ sayin’ . . .
