Wittnauer Ref. 7004A Chronograph

with 15 comments

Wittnauer Pro
Wittnauer Geneve Professional Chronograph Ref. 7004A 239T c1960’s.
(Longines-Wittnauer Watch Co.)
Calibre: Landeron 248, 17 Jewel manual Swiss movement

This is an early example of the 7004A powered by a Landeron 248 movement, with the desirable full lumed triangle on the bezel, baton style min/hr hands, lollipop chrono hand, ‘Geneve’ dial scrip and original signed Beads of Rice bracelet. All these elements add up to a very cool chronograph.

The Landeron 248 was used up to c1969-70, after which the Valjoux 7733 was used. The later models are commonly seen with the arrow head ‘old school’ divers style minute hand and a metal triangle with small lume pip on the bezel. It is noted that some early models didn’t have ‘Geneve’ on the dial or a bezel lume pip at all. An unusual feature of the Landeron 248 is that the top pusher only activates the start the chronograph.  The lower which stops and resets the chronograph.

Another example can be seen here:

Wittnauer is well appreciated by the vintage watch fraternity, and boasts a rich history with some remarkable achievements. Some focus on the more well known name that the Longines connection brings, but Wittnauer stood on it’s own two feet as producing innovative and fine timepieces.

Founded by a young Albert Wittnauer in c1872, he was a Swiss immigrant that moved to New York. Among the companies impressive boasts, are.. supplier to armed forces in WWi & II,  the world’s first waterproof, shock-proof, anti-magnetic watch (1918), Amelia Earhart’s solo Atlantic crossing plane was fitted with Wittnauer timepieces – as was Howard Hughes’ ‘Winged Bullet’ plane that set a US coast-to-coast record. Wittnauers history is scattered with tough environment achievements, earning a well earned reputation of producing reliable, tough, yet fine timepieces.

“In the 1950’s Longines purchased the Wittnauer watch company and marketed a number of very similar lines of watches in the US under both brand names. In this authors opinion, Longines Wittnauer is one of the finest watches a collector can find.  The classic designs are fantastic.  The accuracy and reliability is amazing, and the parts are readily available.  One of my favorites.”

The Landeron 248.. technical info..

Rich Askham comments on the Landeron 248..
“The ’48 Series’ of calibres were some of the most popular that Landeron produced. The series started in 1937 with the cal. 48 and was revised twice to produce the cal. 148 and cal. 248 respectively. Production of the 48 series stopped in 1970 after making around 3.5 million units, and the Landeron name itself disappeared shortly afterwards.

It’s also worth mentioning that the operation of Landeron’s cam-lever chronograph is also slightly different. In most chronograph calibres, regardless of type, the mechanism is started and stopped using the upper button, and reset using the lower button. With a Landeron chronograph, the top button starts the mechanism, and the lower button is used for both stop and reset.”

Wittnauer History
“Founded in America in 1890, Wittnauer timepieces that were used on trips made by navigators, explorers, and astronomers. They were thought to be at the cutting edge of accuracy and style, and were de rigeur with pioneer aviators in the early twentieth century. They created the first waterproof, shock-proof and anti-magnetic watch, and even helped Commander Richard E. Byrd navigate the first flight over the North Pole in 1926.”

Historic Timeline of Wittnauer

Whilst giving it a good clean & check-over, something made me think ‘The bezel size seems familiar’.. so I popped out the crimson bezel insert & tried an aftermarket Autavia 11630 insert.. and I couldn’t believe it.. it’s a perfect fit !!

  3. Great post, great pics. I purchased one of these watches recently at an estate sale. Hoping you might be able to answer a couple questions. When I reset the stopwatch it defaults at about 3 minutes before 12. Is this normal or should it be straight up 12? How long should they run on a normal wind? Do you know how many years this model was in production? Thanks so much for any additional info you can give.

    • The chrono sweep hand should reset to 12.. it probably needs a service.
      The power reserve will depend on which movement it has, as they changed over production. I don;t know the PR off-hand, but if you Google it, it should come up easily. I don’t know precisely how long it was in production.

      • Thanks again.

  4. Hello,
    I’ve recently bought one Wittnauer Chronographe Professional, and would want to change the bezel, like the aftermarket Autavia 11630 insert, because it looks really nice.
    May I ask you where did you find one? What is the measurement of the bezel 11630 you put?
    I’ve some hesitation because when I do measurement of the bezel there’s on my watch, I don’t find exactly the same dimension on a 11630 autavia bezel aftermaket on sell on internet…
    Could you help me?
    Thanks a lot for your response…
    Best regards
    Thierry (France)

    • Thierry. The insert I bought was eBay no. 310304839035, hope that helps.

      • Thanks for your return, and don’t you sell the original red bezel?


        January 15, 2015 at 1:40 pm

  5. I sold the watch with the original red bezel insert.

  6. Where to replace red bezel or insert

    • Where to purchase wittnauer bracelet?

  7. HI, wondering if you can tell me the pusher thread size for this case? I measure them at 2.45 mm but I’ve never measured chrono pushers so I don’t know if that’s what 2.5 mm pusher threads measure, or if 2.45 is the correct measurement. I see that both sizes are available, and both need to be replaced on this watch.

    • Dave, I’m afraid I don’t know, and I don’t have the watch anymore :0(

  8. Great write-up! It’s worth noting that most Landeron movements have the alternativ pusher function, but not all. There are some, like the 149, that function in normal procedure fashion.
