FINGERPRINT

Unlock the world with your unique fingerprint full of minutiae. However, its fragility emerges as time goes - the more it's being used, the more blur it gets. T MARK, however, can stand still with time - never will it be whipped off. The tiniest unchangeable is what makes the mark trustworthy too.

GRAPHOLOGY

From the analysis of the characteristics and patterns of handwriting to identify the writer, graphology is the tool to prove. Yet, handwriting alters along with emotion and T MARK never changes - the infinitesimal and unchangeable mark is something that never fades.

SNOWFLAKE

Enter an astonishing world of nature and find inner peace and breathtaking moments with the crystalline structure of snowflake. Yet, it will eventually melt with T MARK, leaving its proof forever despite its tiny size. This small unchangeable miniature will stay forever.

VINYL SINGLES

Enter a different world of vinyl singles for the "sound to be seen". However, all music ends itself while T MARK will always fuel everlasting moments with the owner. With this imperceptible miniature, you can have a trustable partner to go along this lifelong journey.

T MARK

There's no such thing as everlasting as T MARK Inscription - be it the fingerprint, graphology, snowflake or vinyl single. With the Chow Tai Fook Diamond Viewer, you will discover the world of T MARK wonders : how T MARK, with the thickness of 5 nanometers, is engraved on the diamond without affecting its scintillation and bursts of light that enchant in every movement. Equivalent to 1/20000 of fingerprint thickness, the tiniest T MARK yet the most significant proof.
