Introducing Grandeur Unveils the Lumillion Tourbillon Mashrabia

Grandeur Watches is a rising independent microbrand based in the U.S., founded by designer Belal Shaher. The brand has quickly captured attention with its bold design language and creative horological concepts.

The latest chapter in this journey is a collaboration with the collector Ahmed Gawdat, better known as WatchCollectivetwo. Together, they present the Mashrabia edition of the Lumillion Tourbillon, a creation that bridges cultural heritage with high-end watchmaking. The design draws inspiration from Islamic architecture, specifically the mashrabia latticework of the Sheikh Zayed Mosque in Abu Dhabi. The dial alone required nine months of development, featuring a disc engraved with the intricate pattern, coated in deep Vantablack lacquer, and filled with Super-Luminova to ensure striking visibility in the dark.

The watch is housed in a titanium case measuring 42 mm in diameter and 11.3 mm in thickness. Its construction is tailored to showcase the standout feature, the world’s first lumed tourbillon, a groundbreaking achievement that has already secured a nomination at the Grand Prix d’Horlogerie de Genève 2025.

Powering the watch is a manual-winding caliber based on the Chinese Hangzhou 37Z0E, extensively modified and finely regulated by the Grandeur team. It operates at a frequency of 28,800 vph (4 Hz), delivers a daily accuracy of +3 to +6 seconds, and offers a 42-hour power reserve.

The timepiece is supplied with five FKM rubber straps and a lug module that allows owners to easily switch to alternative strap options, each secured with a pin buckle. This edition is limited to 100 pieces and priced at $2,100, approximately AED 7,750. The watch will officially launch on September 13, 2025, with deliveries beginning in December of the same year.
