I find myself working around magnets a fair bit and I'm pretty sure I mildly magnetized one of my watches not too long ago (need to get a demagnetizer...) and so anti- or a-magnetic watches have become a thing of interest for me. Would like to add one to the collection. I know of some examples, but I'm sure the collective knowledge base here at WUS could come up with several I'm not familiar with.
To clarify "anti-magnetic" up front, when I say anti-magnetic, I mean legitimately enhanced magnetic resistance. Not the "anti-magnetic per DIN 8309" nonsense that certain brands like to flaunt as though it's something special. Every watch in the past 50 years, and every watch I currently own, meets DIN 8309 (4,800 A/m, or 60 Gauss). I'm looking for at least 50,000 A/m (600 Gauss).
What I'm looking for:
50,000+ A/m (600 Gauss) anti-magnetic rating
36-38mm case diameter (excluding crown) if a fixed bezel, or 38-40 with a rotating timing bezel
48mm L2L max (45-46 is my sweet spot)
Thickness <13mm (if a domed crystal pushes total thickness a little above that, I can deal with that, so long as the metal is <13mm thick)
At least 5atm/50M WR (10atm/100m preferred)
Time only or time and date. No other complications
Price: Trying to keep it under $1000. Might be willing to stretch my budget 10-15% beyond that.
New or used, but no vintage. Bracelet preferred.
What besides the 36mm Armida A6 hits all the marks?
