Photo of Instrument Board "Spirit of Saint Louis"

New postby fjmenez » Sun May 09, 2010 4:57 pm

In this photo, a Waltham Airplane Clock Model XA is located on the right side of the Instrument Panel. This Waltham Airplane clock has 15 Jewels and is Adjusted. Built to the rigid US Aeronautical specifications. For 22 days it was tested for accuracy under conditions of continuous vibrations and temperature. The clock has radium dots and hands. This clock was sold to Charles Lindbergh, San Diego, California on 4 April 1927. It was an 8-day clock. The clock was installed flush on the Board and there was a cut out to reach the winding knob. When not in use the cut out was secured with a cover. The Charles River Museum of Industry & Innovation has a Charles Lindbergh display. The museum has a Model XX which is identical to the XA Model with the exception that is has only 7 Jewels.

John
For years there has been some confusion as to what model of Waltham airplane clock was installed on the Spirit of Saint Louis. I have done research on this matter and have been in contact with Ev Cassagneres of California who is an Ryan Aircraft Historian and a Lindbgergh/Spirit of Saint Louis Specialist. The Waltham Watch Co records and photos indicate that the Spirit of Saint Louis had a Model XA 15 Jewel Waltham Airplane clock installed on the panel/board. The XA and XX wind from the bottom of the clock as can be seen in the photos, they both have 15 Jewels. There are two models of the XP one has 15 Jewels and the other 7 Jewels. They both have a flush winding knob at the 6 O clock position. They do not require a cut out to wind. In summary the description given in the Ryan/NYP web site is in error , the clock shown is a Model XA 15 Jewel clock. In some photos of the XA on the panel show a cover with a knob that covers the cut out. Some people believed that the knob of the cover was the winding knob for the clock. The document that shows the items that Charles Lindbergh purchased shows a 1 day Waltham Clock, with mount # 314. The mount was necessary to secure the clock from the rear of the panel. The clock sold for $32.

PS There are some people that think there may have been two different clocks installed on the panel, however I have not seen any evidence that this is the case. I think Lindbergh would have perfered a 15 Jewels clock that met the rigid US Government standards. The 7 Jewel clocks was considered to be the standard model. I have talked to the curator of the Smithsonian in Washington and he stated that the records show a model XA.

Just found the following info in my files.

Waltham also produced a 7 jewel Model XX Airplane clock. They also produced a 7 Jewel XZ Airplane clock Flush fitting type.
