The Monnin case style dive watches are interesting and from a historical perspective did save Heuer during the quartz crisis. Being a James Bond fan, I have always fancied owning a Heuer 1000 series automatic watch (Heuer Night diver in the Living Daylights) but @ over 1k US$ for a watch in an average condition, it does seem like a distant dream for now.
I have been hunting for one of these watches on the forum sales thread and did come across some examples of a Monnin case dive watch. I am looking for something with the following specs:
1. Case size - 39 mm to 42 mm
2. Movement – Auto or Quartz
3. Budget – 500 US$
The Monnin style case brands/watches I know - Heur/Tag Heuer, Zodiac, Technos, Felca/Geota, Aristo, CWC,
A couple of questions:
 Would it be possible to swap the hands/dial of a quartz 40mm Technos Sky Diver/Zodiac Red Dot with a replacement/compatible Heuer set ? (assuming the movements are the same)
 What are the movement variants currently available for Monnin Cased dive watches ? (quartz & auto movement variants)
I am ok with modern/current production examples having the Monnin Styled case. Please share your suggestions/recommendations.
