Founded under the horological umbrella of Charles Watch Co., TESSARO was conceived with a single guiding ambition: to bring the breathtaking mechanical artistry of open-heart haute horology to watch connoisseurs worldwide, without the inflated intermediary markups of legacy Swiss conglomerates.
In a world dominated by disposable digital gadgets and silent quartz batteries, we believe that true luxury is tactile, emotional, and mechanical. An open-heart watch is not merely a tool for measuring seconds — it is an intimate living machine whose golden balance wheel beats in harmony with your daily life.
Every TESSARO case is CNC-machined from solid blocks of medical-grade 316L stainless steel or finished in heavy 18k gold PVD plating. We crown our timepieces with scratch-resistant, anti-reflective domed sapphire crystals and pair them exclusively with ethically sourced, hand-stitched Italian leather straps.
Reveals the escapement wheel and ruby pallet jewels beating at 21,600 vibrations per hour.
Rated 9 on the Mohs hardness scale (second only to diamond), ensuring decades of pristine clarity.
By bypassing distributor margins, we invest directly in superior movements, dials, and hand finishing.
Our unwavering confidence in Charles Watch Co. quality is backed by our comprehensive decade-long movement guarantee.
