You don't see many watchmaker shops, but there is one hiding in a Greenpoint apartment.

Max Von Isser repairs and restores vintage watches under his business name 'Wear Has The Time Gone' at his workshop that is located in his apartment.

He mainly deals with online sales and orders but has started doing pop-up sales and repairs near McCarren Park.

Von Isser says there's a demand for vintage wristwatches, but the workforce is "dying out or retiring."

Von Isser started watchmaking as a hobby before doing it full-time four years ago.

"It's crazy how delicate and intricate and tiny some of these parts are, especially when they were making them back in the 1700s and 1800s. This is from the 1950s, but it's insane looking inside. It's crazy, and there are so many parts. Someone had to figure out these machines without computers," said Von Isser.

He's self-taught and recently started a YouTube channel with tips to help others.
