Their perceived value — through quality of design, materials, and manufacture — is a key component of their success. Each of their watches is assembled by hand and extensively controlled with latest equipment to ensure maximum quality. Frédérique Constant innovates to offer creativity and exceptional value. Their factory in Plan-les-Ouates Geneva is ultra modern and offers the best environment for their passionate watchmakers.


The Frédérique Constant Index collection comprises of five models. All models are powered by the delicately decorated FC-303 automatic calibre, beating at 28’800 Bph and viewable via a see-through case back. The design of these classical models is ultra clean and functional.

Welcome at
We are proud and honoured to welcome you to our new and fourth store, the Ace eBoutique:!

Ace Jewelers has been online since 1998 and after 10 years of developing we present a secure and innovative e-commerce website on internet. A website where we try to serve you with the same service you are used in one of our two physical boutiques. In 2013 we relaunched a complete new eBoutique.

With the launch of our third store on the internet and the creation of a dedicated sales team for our website, Ace Jewelers Group starts with its new Multichannel strategy. This means that we transformed and evolved from a classical retail organisation into a hybrid enterpris that embraces e-tail (e-commerce), retail and a call center. We decided to implement a new strategy bearing one reason in mind: To serve you in a better and modern way.

Here at Ace Jewelers, in name of all our associates and The Ben Joseph Family, we want to welcome you again in one of our two boutiques in the heart of Amsterdam, The Netherlands. In case you will not visit the Diamond City of the World, please do note that we ship orders (often) free of charge all over the world. And, for non-EU residents, we even send them tax-free!

Yours truly,

Ace Luxury Group
