So it seem like no relationship to the AVUS II

But made also in 1997 (same as the AVUS II family)

CERTIFICATE OF ORIGIN

"Aviation '45," Half a Century of Watchmaking Art

Minerva AG hereby certifies that your "Aviation '45" chronograph, powered by the original Valjoux GHH No. 71 caliber, was entirely assembled and finished by our current Head Watchmaker, Mr. Yvan Bourquin, both in terms of movement and accessories.

The original GHH No. 71 movement was only supplied by Valjoux from 1938 to 1949. This rarity and its unusual size of 32.60 mm in diameter, or precisely 14 1/2 lignes, create an exceptional caliber.

The creation of the "Aviation '45" design was inspired by a Minerva 17-ligne model from the 1940s.

Mr. Bourquin has been working at Minerva since February 11, 1952, in the workshops that our manufacture has occupied since 1902. Mr. Bourquin's 45 years of experience ensure this assembled movement an uncompromising authenticity of which we are proud.

We thank you for your trust and wish you a long and successful relationship with your "Aviation '45."

Villeret, November 25, 1997
