Heritage Watch Manufactory Magnus Contemporaine & Magnus Classic

The Magnus by Heritage Watch Manufactory is a perfect watch and absolutely perfect timepiece for everyone who loves perfectly constructed mechanical objects in their purest form.

Its precision balance, the special mechanisms for fine regulation of the escapement, the balance cock and even the balance wheel are completely unique.

Magnus Contemporaine

This design is available in two variants — while the dial of the Magnus Contemporaine shows a perfectly executed interplay of space and volume, the Magnus Classic reflects the business-like finesse of the watch.
