The Kreizer family became a veritable dynasty of watchmakers, with at least four apparently bearing the same Christian name. Some uncertainties exist as to whether Conrad III and IV were not in fact the same person, but certainly one of the Kreizers occupied the position of clockmaker to the Knights of the Grand Cross of Malta and indeed several watches signed by Kreizer use their characteristic cross as the form for the pendant. The watch now offered for sale has a pendant of similar construction, perhaps the form used for watches destined for 'secular' clients, but in all other aspects it is typical of his work.
Accurately dating certain watches by Kreizer can be difficult, as he appears to have continued to produce pieces of 16th century design long after they were superseded, perhaps due to the requirements of his important clients, which would certainly have brought him wide recognition.
Certain interesting features of the movement tend to support a date from the second quarter of the 17th century, for the stackfreed has been abandoned in favor of a fusee.
