    Default Hamilton 987 E

    Does anyone have any info on a Hamilton 987 "E", I can't find anything in my books. It looks just like an "A".
    Thanks, Tom

    According to Rene Rondeau, 987 "production ran from 1926 to 1948, in several slight variations (987A, 987E, 987F, 987S, etc.). A total of 1,160,392 were produced."

    The 987E model was produced from 1928-1937 with serial numbers 4025301-4523000.

    Hi Tom:

    The 987 movement was introduced in 1926 and was initially described as a 6/0 size movement with 17 ruby and sapphire jewels. It replaced the 986A movement which ceased production that same year.

    The 987E included an Elinvar hairspring (The "E" in 987E stands for Elinvar) as well as a monometallic balance wheel. It was first manufactured in 1935 and production continued until 1937.

    I hope I have been able to answer your question.

    Regards,

    Will

    Thanks guys. I have a 987 and a 987S, but I have never come across a 987E, and wondered what the "E" designation stood for. Learn something new every day.

    Hi Tom:

    The 987 series was Hamilton's "workhorse" and is a phenomenal movement. They are easy to work on and are found in many of Hamilton's classic models.

    The 987S (The "S" stands for Sweep Second) was introduced in 1940 with serial number SS001 and production ceased in 1948 with serial number SS87400. The 987S is often found in military watches and is unique in that it contains a "hack" feature that enables the wearer to stop the second hand when setting the watch.

    Good luck with all your 987s,

    Will

    I have attached a picture of the Hamilton Vancott, one of Hamilton's most rare watches (23 examples in 14K gold as this example is). It utilizes a 987S movement with a hack feature.
