I just had my Explorer II adjusted, and asked the watchmaker to confirm that it had caliber 3186. According to the so called wiggle test it should. It is an M0-serial purchased in february 2008, and the code on the clasp indicates august 2007.

The watch has indeed caliber 3186!

This is therefore another example where the test truly indicates caliber 3186.

In addition I asked him to verify the height of the caliber, since it was told initially that caliber 3186 is 0.4 mm higher than caliber 3185 (to allow for the new construction for the hour hand). This information comes from (to the best of my knowledge) the early facts from Basel when the all gold GMT IIc 116718 was introduced.

I have been intrigued by the fact that a larger caliber has been found in cases of the older style, and according to my calculations the margins would have been zero - or even negative. There should not be room for the new caliber in the older cases.

The watchmaker now confirmed that the height is the same for both caliber 3185 and 3186: 6.4 mm, not 6.8 that has been "public knowledge" on sites like this.

I hope this information is of interest not only for me.

Best,

A

No, caliber 3186 is not only about the new balance spring. The construction for setting the independent hour hand is completely new. That's why the "wiggle test" is so indicative of the new caliber.

ok..can someone please explain the "wiggle test" as I am confused....I own a d serial expy II cal 3185. I am confused as to what this test refers to..My expy has the jumping hour hand and the 24 hour and minute hand adjustable...I though this was the norm...

The difference is that the construction of the jumping hour hand mechanism is decoupled from the 24 hand in the 3186 movement. The wiggle test is to move the jumping hour hand to see if the 24 hour hand wiggles. If it does, it has the older style mechanism.

Simply:
In the 3186 some of the gearing has changed as well as the parachrom spring. The "slap" in the gears has diminshed and the hands do not wiggle as extensively as in the 3185 when adjusted.

I still wonder how JJ do the wiggle test with his sheep?

He opens up the aperature and wiggles the appendages.
