Working On The Vintage Valjoux 72 Chronograph Watch Movement.
I didn't like how this movement was running so I disassembled, cleaned, and reassembled with all the Moebius oils and greases, The amplitude was lower that I liked so I found a mainspring that was made for this movement that was slightly stronger and bought a new barrel and arbor and installed the new barrel assembly, I have two balance wheels, one with a older "blue" hairspring and one with a newer "silver" hairspring so I'm going to test both to see which one I like best.........

Amazing accuracy 2531.80
My Seamaster Professional 300m (2531.80) hadn't been getting much wrist time in the past year for whatever reason. I travel a lot, and always wear my Rolex GMT Master II (16710 with a Pepsi bezel) when on a business trip. I like to easily see my home time zone at a glance without thinking. At home, I generally wear my Seiko Marinemaster (SBDX001) as a daily wearer. It has a great wrist presence and wears nicely for its large size. I felt nostalgic for the Seamaster, and have been wearing it the past two weeks while on vacation. I had it last serviced by Omega three years ago, and it's keeping great COSC time. I set it to the atomic clock and have been checking it daily at the same time. It's running at +.01 sec / day. The 1120 movement is simply amazing. I love this watch and will never sell it.

production number per category ( a sensible calculation)
Quit ofter do some of us ask how many ref XXX or ref YYY are made per year.The answer is that we don't know but we can try to make an educated guess.One thing we know is that Patek makes about 50.000 watches per year and that the biggest part , a bit over 30% I once read in an interview with Mr Stern, are the Twenty-4 for womanSimple watches like the Calatrava are for sure the second biggest groupSo this is a calculation I made, feel free to argueTwenty-4 ( a bit more than 30%) so let's assume about 17.000 piecesCalatrava (more or less 20%) 11.000 watchesGondolo 5000Nautilus , my guess ¡­ 4000 per year ( to make is simple 1000 per complication so 1000 chrono's in all materials, 1000 simple 5711 in all materials, 1000 5712 and 1000 annual calendars)Annual calendar ( all references all materials) 3500Worldtime ( all references) 3500Chronographs 2400 in total ( ref 5960 in all materials about 1200, 5170 about 700 and 5270 about 500)Golden Elipse ( not very popular) also 1000 in all sizes
