Views on 1940s and later bumpers

If those considerations are high on your list, why not choose a manual-wind vintage watch? Easier and typically less expensive to service; less can go wrong with the movements; better power reserve capability, etc.

I’d agree with @Tony C. - the 30T2 manual winders from this period are rock solid and easy to service. I also love the connection one has with the watch with a manual wind movement, keeping it wound and ticking as a little ritual each day. I’m a recent convert to these and I love my 1948 Dennison-cased watch:

Personally, I love the style of the old bumper movement Omegas and the characteristic "thump" that you feel while wearing the watch. I have several including this rather unique 1952 Seamaster 2635 with a honeycomb dial and Breguet numerals:

That being said, Tony C. and wilderbeast make good points. The old bumper movements are less reliable than both manual winders and rotor based automatics. Parts are becoming harder to find and repairs can be expensive. The above watch is a good example. The movement was badly in need of a service when I bought it and it needed a few parts. The service bill was more than $500 and that, added to the cost of the watch, resulted in me spending more money than the watch is worth. I don't regret it and the watch runs well now and keeps great time, but bumpers can be a bit of a minefield and many watchmakers are shy about working on them.

My daily is a bumper as long as forecast is dry.
I have said it often, but the gentle bump makes the watch seem a part of me!

If you want to wear vintage, you will need a relationship with a watchmaker: This choice may affect how you want to go forward.

All the advice is good and very true but it is the bumper for me!

(I do like bumper movements, and other fans of them might want to note that I will be listing a very nice one FS later today!)

I would look at ref 2639 from early 50s with movement 265 and later 266 which are descendants of famous 30 line.

Advantages:
They are abundant
Movement reliable and easy to service
Handwind which I like in vintage
Lots of dial options
Larger size 38 mm

I have a nice black gilt dial version (birth year for me 1953) here are some photos and a nice overview article.

~36mm, IIRC. Still a very nice and wearable size.

You are correct thank you.
