As far as i know movement for 74 are in range 31xx xxxx – 39xx xxxx http://speedmaster101.com/145-022/145-022-71-74-76-78/ About the brake. https://omegaforums.net/threads/speedmaster-pro-delrin-brake.44982/ Last third post, the article states that the 74 has metal brake before serial model 3285xxxx. So according to this, mine is correct.
