Christmas elegance in gold and red

Just in time for Christmas, the independent Glashütte watch manufacturer Moritz Grossmann shows its most glamorous side. With the ATUM High Art Christmas, the manufactory dedicates its own masterpiece to the most beautiful time of the year, embodying the high art of watchmaking to perfection. Warm rose gold, ‘Christmassy’ red and a high-artistic finish lend the special model of the ATUM line its festive elegant charisma.

The noble one-off piece is not only a homage to Christmas, but also a timelessly stylish eye-catcher that makes every day something special. The colour red has symbolic power; it stands for love, passion, fire and radiates pure joie de vivre — just like the ATUM High Art Christmas.

The case in 750/000 rose gold gives the Christmas red dial its elegant setting. The indexes, also in rose gold, harmonise with it. The handcrafted lance-shaped hands are tempered by hand over an open flame in brown and are given their unique three-dimensional shape by manual chamfering.

The red bracelet reinforces the effective colour concept. The Grossmann manual winding mechanism with pusher ensures comfortable handling and enables a perfected pointer setting mechanism.

The calibre 100.1 in the high-artistic finish makes the watch a real gem, because all parts are polished, chamfered and ground by hand in elaborate detail work. The sapphire crystal back on the back of the watch reveals the fine mechanical components of the ATUM High Art Christmas — a sparkling ensemble, not only during the Christmas season.

With the ATUM High Art Christmas, Moritz Grossmann once again demonstrates an extraordinary flair and craftsmanship for timepieces that represent “Schönstes deutsches Handwerk” — meaning the most beautiful German craftsmanship — in an incomparable way.

The ATUM High Art Christmas comes with the calibre 100.1 in a High Artistic finish in the single copy 1 of 1.
