Horology 101 - automatic winding system
There are several different full-rotor winding mechanisms in use today; this is a breakdown of one bi-directional system using a mechanical reverser. Since a reverser can change directions over a million times a year in a daily worn wristwatch it must meet the following criteria:- long lifespan- low maintenance- ability to withstand shock- small dimensions- flat profile- simple design with minimal parts- low friction- low moment of release (can easily change directions)- low moment of rotation (amount of energy require to set in motion)Here's a diagram of the winding mechanism:1 - crown wheel2 - intermediate wheel3 - auxiliary intermediate wheel4 - ratchet5 - ratchet-driving pinion6 - 3-arm spring7 - ratchet-driving wheel8 - reduction wheel & pinion9 - winding wheel & pinion10 - stop pawl11 - stop pawl spring12 - reverser13 - reverser14 - pivoting mobile platform15 - intermediate pinion16 - oscillating weight pinion17 - oscillating weight (rotor)18 - winding stem19 - winding pi

philip admoralie 48mm crown
this will be the last watch purchase for a wile being every thing i touch seems to fall apart. auto. movement val. 7750 keeps verry good time but the end of the crown fell in my hand. the watch is not even a month old and i am paying to ship it for repair already.not much faith in swiss made watches at the moment.the watch dady said the crown was tough to pull out but he did not tell me that it could fall apart. i own 2 of these watches and donot know much about the movement and how and why the crown is so hard to pull out.does enyone else have the same watch problem.i hate the time change, to many watches, jim

Incoming!!! Unexpected Retro Edition
Stopped by to visit my parents after leaving work today, and was given a couple older watches that belonged to my Grandfather. Snapped some quick pics, so they're not that great, but they'll work for now.The first two have got 1970's written all over them, but the last one is somewhat interesting. I'd be curious to learn more about all of them (info, approximate age, etc.) Any help is appreciated....Watch #1.Timex Digital on what appears to be a two tone, simulated crocodile skin, metal Speidel stretch band. Yeah baby...Watch #2...Seiko Quartz / Digital combo...on stainless steel "Flexon" strap.Crazy thing...these watches have been in a box for years. When I was first handed the Seiko, it was ticking right along, and the digital readout was on. I pulled out the crown to set the time, and it stopped. Must have been too much for the old battery to handle. :)

New AP...what do you think?
New to the thread. Longtime AP lover. I just picked this up on Thursday, it is technically my 2nd AP. I bought the 44mm stainless the day it came out and loved it as my daily beater for 2 years until 6 months ago I decided to sell to clear up some cash to finish my new house. Right after I purchased mine I bought my wife the new ladies royal oak with diamond bezel(I did not sell hers lol) needles to say I finally got to buy what I consider to be my favorite current AP 44mm. I love the silver dial and contrasting sundials and bezel. Also I noticed a huge difference is the brushing definition on the ceramic bezel. So much deeper then in 2012.
