Our remarks

We are proud to offer you this very good Patek Philippe Perpetual Calendar Moon-Phase Ref.3940 in 18k rose gold with croco leather strap and PP deployment buckle.

Comes with the original wooden box (inside is disintegrating), setting tool and an extract from the Archives - 1991.

The Ref. 3940 is a star. Having perfect proportions and a more than classic look, this perpetual calendar is still considered to be one of most typical Patek design ever.

We love the flat automatic case and the lack of a second. Keeps the watch so fine.

Great collectors Patek and of course a fine investment piece for the wrist.


1 year warranty from the Bachmann & Scher GmbH.
