The book "Philipp Matthäus Hahn 1739-1790" was published in two volumes by the Württembergisches Landesmuseum Stuttgart and Christian Vaeterlein in 1989; Vol. I is entitled "catalogue" ("Katalog"), Vol. II is entitled "essays" ("Aufsätze"). Vol. I shows a watch with a similar dial with red and black hours (1-12 / 1-12) on page 491. On page 475 a watch with a very similar case, held by the Württembergisches Landesmuseum in Stuttgart, is illustrated and described.
Research associate Dr. Guenter Oestmann is the author of several essays in both volumes; his works are devoted to pocket watches by Philipp Matthaeus Hahn, his staff and his successors.
The watch was presented to Dr. Oestmann in Bremen in March 2015; Dr. Oestmann confirmed the authenticity of both original case and movement. According to his expertise this watch is the only one we know that is glazed on both sides.
