Solvil et Titus Archive

Records of Paul Ditisheim's legacy and the brand's international history.

Overview

Solvil et Titus Archive is a archive based in Hong Kong, China. Records of Paul Ditisheim's legacy and the brand's international history.

As an archive, its value lies in documents rather than displayed objects: ledgers, registers, patents, correspondence, drawings or production records.

Production and sales ledgers can confirm when and to whom a specific numbered watch was delivered — evidence that marks on the object alone cannot give.

Using it for research

  • Ask whether the archive issues extracts or certificates for individual serial numbers, and on what terms.
  • An extract confirms what the records state about the original object; it does not by itself prove that every part of a watch today is original.

Before you visit

  • Archives are usually accessible by written request or appointment only.
