With deep expertise in vintage watches, Shellman offers everything from world-renowned masterpieces to uniquely designed original watches.

About the Shellman Grand Complication
The “Grand Complication” is Shellman’s flagship original model, featuring complex mechanisms that represent the ultimate dream for watch collectors. Shortly after its release, it received numerous awards and was selected as a permanent exhibit at the International Watch Museum in La Chaux-de-Fonds, Switzerland. It is highly regarded not merely as a decorative timepiece, but as a watch that allows the wearer to experience the true depth of horological technology in practical use.

About the Shellman Grand Complication Premium
The Shellman Grand Complication Premium is a refined, higher-grade evolution of the original Grand Complication. Every aspect—appearance, details, and functionality—has been carefully reworked, resulting in a flagship model that offers both sophisticated elegance and excellent practicality for mature collectors. From the case and dial design to the shape of the hands, every element is specially designed, achieving a level of finish comparable to high-end Swiss luxury watches.

About the Movement
This watch is powered by the Citizen Cal. 6771 movement.
This movement is known as the world’s first quartz grand complication movement and includes the following functions:
Because the base movement is manufactured by Citizen, servicing such as overhauls and repairs can be performed by Citizen. Although an operation manual is not originally included, Citizen has published an official instruction manual for Cal. 6771 online, which can be used for operation reference.
This movement is also certified as a permanent exhibit at the International Watch Museum in La Chaux-de-Fonds, Switzerland, one of the most prestigious watch museums in the world.
