This is a wonderful question, that deserves a careful response.Before we can talk about the natural escapement, let's get on the same page about what an escapement does. In a mechanical wristwatch, an escapement translates rotational energy into lateral impulses that is, it turns the rotating of gears into the back-and-forth movement of the balance wheel.  There are lots of different types of escapements, but the most popular (by far) is the lever escapement.

Advise on a serious trade for a 5131J.
Hi there guys hope you are all having a great week..Being an airline captain I have been a very keen admirer of the World Time 5131's and have tried like crazy to get hold of a 5131R and even wrote personally to Mr Stern, to which he replied personally via fedex but unable to help me.Just wanted some advise as I have come across a 5131J like new not sealed. Would you trade a 5980R and 5712 which I bough double sealed plus 36K USD for a 5131J. OR 5980R + Rolex Smurf 166619LB (3 years old) plus 46K USD for 5131J.Looking fwd to hearing from the more experienced collectors if the above deals are worth it and do you see the 5131J appreciating in value in the future to justify this trade? ThanksAndyIG: JETKOPITE777
