A Study in Light, Geometry, and Natural Beauty
A composition shaped by nature
GEOMETRY MEETS IRIDESCENCE
Built from individually selected pieces of natural mother-of-pearl, Tessera combines geometric precision with the unpredictability of nature. Every fragment reflects light differently. The pattern remains constant. The colours never do.

FAQ
Do the watches have luminous markers?
Yes. All models include luminous hands and markers for visibility in low light.
Are your watches automatic or quartz?
We offer both. Some of our watches use automatic movements (like PT5000, NH34, NH35), powered by wrist motion. Others use quartz movements (like VH31, Ronda 515.24H), powered by battery. We also have solar-powered options like Epson VR42. You’ll find the movement type listed on each product page.
What kind of movement do your watches use?
We use a range of reliable mechanical and quartz movements, including PT5000, TMI NH35/NH34, TMI VH31, Ronda 515.24H, and Epson VR42, each chosen for its performance, accuracy, and fit for the watch’s purpose.
How should I care for the watch?
Avoid strong magnetic fields, wipe it regularly with a soft cloth, and have it serviced every few years for best long-term performance.
How can I track my order?
Once your order ships, you’ll receive a confirmation email with a tracking number. You can use it to follow your delivery through the carrier’s website.
