divisor line



Seth Thomas has been noted for its ship’s clocks for well over 100 years, and in its early days,
was the sole provider to the U.S. Navy


Presented is a very rare, and very small antique,
eight day clock that is dated 1911. It is the first Navy Boat Clock we have seen by this maker making it very
rare and suitable for the best of collections or as an important gift. It has a high grade 7 Jewel movement with machine
cut pinions and gears, a non-magnetic Breguet type hairspring, and compensated escapement with fancy scroll engraving on the
platform marking this a precision timepiece.

The seconds hand is at below 12 O’clock position with the Fast-Slow lever above.
It is housed in a very heavy, forged bronze case with screw on bezel.

RECENT SERVICE: The clock has been just
serviced by a master clock smith which included a tear down and ultra sonic cleaning with worn bushings replaced and all parts
cleaned and lubricated. T
movement is keeping good time rated against a quartz comparison watch.

Very few Seth Thomas Navy Boat clocks are
know to exist and this one is in fine condition considering its age and use at sea. It will make a suitable gift or is
worthy of inclusion in a collection of fine marine clocks




SPECIFICATIONS: Forged bronze case with screw on,
moisture resistant bezel. The 4 1/2 inch outside diameter has a 3 1/2 viewable area. The dial is silver
plated and has  Silk Screened Arabic numerals and Copperplate lettering in black enamel. The precision 8 day, Ship’s
Lever No. 3 movement with 7 jewels has a compensated balance wheel and Breguet hairspring.

Back of heavy forged case. Number 2866 at bottom


CONDITION: This internal bell clock is in especially fine condition with minor blemish’s
on the face where some of the silver is worn. There are scuff marks, foundry imperfections ands nicks on the case,
but nothing of consequence. The bezel’s threads tighten as the bezel is screwed all the way down. A photo shows
it in the raised position. The clock is running strong and keeping good time compared to an accurate quartz watch, and will
run for a bout six days on one winding. We recommend it be wound about every four days for best timekeeping. It is
considered in very good condition overall.


bezel is to the bottom and is not fully tightened
