What Our Clients Say about Us
-
“So pleased with the service I received after visiting 3 different watch repairers to have a bespoke strap fitted to my collectable watch. All said it couldn’t be done. AMJ were friendly, helpful and quick. They fitted the strap within 5 minutes and charged a very reasonable price. Highly recommended.”

"Top marks for AMJ watch repair for quality of work, customer service, and old-school decency! Not only did they do a stellar job (three different watches), but they were also very kind and generous when, due to my miscommunication, revisions were needed the following day. Highly recommended!"

"Incredible watch repair shop, very friendly and knowledgeable. My watch would not calibrate, and I believed it was a battery issue. The team and AMJ reviewed it and emailed me to say it’s ready to collect. Honest and reliable, and I couldn’t recommend them highly enough."

Your Cartier Maintenance & Repair Questions Answered
Find clarity on our Cartier-specific repair standards, service timelines, and the precise measures we take to preserve your Tank or Santos case and manufacture movement throughout its journey.

Our Cartier overhaul begins with a complete disassembly of the movement. Each part undergoes a rigorous ultrasonic cleaning cycle to remove aged lubricants. Our watchmakers then meticulously reassemble the calibre, applying manufacturer-specified Swiss oils to ensure peak reliability and smooth operation.
-
We perform multi-stage pressure testing to original factory specifications—from a 30m Tank to a 300m Calibre de Cartier Diver. Using Swiss-standard equipment, we verify the integrity of your case and gaskets and provide a physical pressure-test certificate as documented proof.
