I took my Bvlgari Chronograph to a specialty watch repair in California and had to send it back after $800.00 in repairs. Still wouldn’t keep time Manhattan Watch service repaired, cleaned and polished. Even installed a new bezel which the former watch shop said it was not available. New, authentic band too. Not some knock off band. These Master watch repair techs and customer service is exemplary. Highly recommended. Eugene, Oregon.
