It is presumed that multiple captain's watches were made during the 17th and 18th centuries, by both Dutch and non-Dutch makers.

This appendix describes two additional Dutch captain's watches.

A Dutch silver and partly gilt oval puritan  watch, the fire gilded movement with fusee and pre-hairspring hogs bristle regulation verge escapement, signed:

Jan Janz Boekels Hage¹

Collection Rijksmuseum.

Dimensions: 40 x 32 mm.
The pointer of the hour hand is missing.

It features an engraved silver dial, displaying the high tide times for the following three locations:

^•  Amster  Amsterdam
^•  Santû    Santv   Santvoort
^•  tûlie      tvlie      't Vlie   (View chart)

Unfortunately, no pictures of the mechanism behind the dial are available. This may be because the corroded locking pin securing the hour hand is difficult to remove, preventing the movement from being disassembled.

Unlike the gold Nauta¹ watch, the extensive corrosion of this watch’s components suggests that it may have been used in offshore conditions.

 1)   Jan Jansz Boeckels the Younger.

Haarlem and The Hague, active first half of the seventeenth century; died by 1651.

Jan Jansz Boeckels was a Mennonite watchmaker active in Haarlem and later in The Hague during the first half of the seventeenth century.

He belonged to a family of watchmakers and is documented in connection with Haarlem from the early seventeenth century. Following a legal dispute in 1625, in which he was acquitted of serious allegations made by his wife, Sara Adriaens, he left Haarlem and established himself in The Hague, where his presence is documented in 1627.

Boeckels produced technically sophisticated watches, including examples with lunar and tidal indications. A clock-watch attributed to him, dated circa 1625–1635, is preserved in the British Museum; an oval silver watch signed *Jan Jansz Boekels / Hage*, incorporating calendar and tidal indications, is in the Rijksmuseum. His former apprentice, Jacob van Caschbeeck, subsequently went to London with Sara Adriaens, and the couple's marriage was dissolved in 1632.

Boeckels also appears to have had artistic interests and probably visited London. His grandson, the engraver Cornelis van Dalen II, produced an engraving after a drawing by Jan inspired by a painting by Peter Paul Rubens. An inventory and sale of Boeckels's estate in 1651 establish that he had died by that date. His precise birth date remains unknown, and the attribution of some early watches to him or his father, Jan Jansz Boeckels the Elder, remains uncertain.

A watch of his father resides in the MET musuem
 

2)    ‘Dutch Gold, Silver and Clock Museum’

The Amsterdam Museum of Timekeeping (1901) and the Dutch Guarantee Museum in Utrecht (1938) merged in 1953 to form the Dutch Gold, Silver and Clock Museum.

Initially housed in the Catharijne Convent in Utrecht, the museum eventually outgrew its premises and relocated in 1970, making way for the Museum of Music Boxes and Street Organs.

In 1978, the museum moved to Schoonhoven, a town whose reputation as the Silver City made it a fitting home for the collection. In 2011, the museum was renamed the Dutch Silver Museum Schoonhoven.

By 2013, the SMAT Foundation’s horological collection was no longer on loan to the museum.
