Hallo Allemaal.
Ik ben flink aan het nadenken om in te gaan op de aankoop van een Heuer cal.12. Misschien is dit topic al eerder besproken, ik controleerde het maar kan geen specifiek antwoord op mijn vraag vinden. Indertijd begon men met cal.11 waarna men overstapte op cal.12. Wat zijn beide verschillen van deze werken en wat zijn de nadelen van cal.12? Duur in onderhoud/onderdelen?? Zijn er gevoelige onderdelen bij die het wel eens kunnen begeven? Wie kan me hierbij helpen aub?
Vriendelijke groeten, Bart.
Via Google vond ik zowel deze: Monaco calibre 11 v calibre 12 v calibre 36 v Heuer 02 | TAG Heuer Forums. Maar - dichtbij huis - ook deze: Tag Heuer Monaco Caliber 11 vs Caliber 12.
Veel meer dan verwijzen kan ik niet, aangezien ik niet erg thuis ben in de wereld van Heuer.
dank u wel voor de hulp. Veel wordt er niet over gezegd maar het is toch al beter dan niks!
Volgens Omega Forums was het vrijwel hetzelfde caliber met wat kleine verbeteringen in de 12 t.o.v. de 11.
Hier staat een gedetailleerder artikel over de ontwikkeling.
Changes from the Caliber 11-I movement to the Caliber 12 movement included the following:
- Faster Beat. The “beat” of the movement was changed from 19,800 vibrations per hour (VPH) in the Caliber 11 and 11-I, to 21,600 VPH in the Caliber 12. The change to a higher beat was consistent with trends in the watch industry, suggesting a preference for higher beat movements. The change in the “beat” of the movement required a re-design of the mainspring and balance wheel, as well as corresponding changes in the fourth wheel (225), the escape wheel and pinion (705) and the pallet fork and staff (710). These components are unique to the Caliber 12, and earlier parts for the Caliber 11 or 11-I may not be interchanged with these parts.
- Strengthening Other Components. Certain components of the Caliber 12 movement were made stronger or otherwise improved. For example, the fly-back lever (8180) was made wider, as the narrower levers on the Caliber 11 and 11-I had sometimes failed. One of the most visible changes from Caliber 11-I to Caliber 12 was in the reshaping and enlargement of the hammer (8220). In the Caliber 11 and 11-I movements, the hammer cam jumper (8356) rested against the lower section of this hammer (8220), but there was nothing to prevent the hammer cam jumper (8356) from “jumping” out of position, coming to rest above the hammer (8220), which would result in the start / stop / reset being inoperable. In the Caliber 12 movement, the “head” of the hammer (8220) was made significantly larger, so that it “sandwiched” the hammer cam jumper (8356) in place and prevented it from jumping out of position. A large hole in the head of the hammer (8220) allows for oiling of the area of contact between the jumper and the hammer, and is an easy way to identify a Caibler 12 movement.
- Color Change. The most visible change from the Caliber 11 and 11-I movements to the Caliber 12 movement was that the main plates of the movement were changed from a nickel / silver color to a gold tone. The Caliber 12 looks like a gold tone movement, compared with the silver tone of the Caliber 11 and 11-I. (There are, however, certain Caliber 12 movements that use the same nickel-silver plates as the Caliber 11 and 11-I. In these instances, the “11” on the chronograph bridge (8500) is over-stamped with a “12”.)
