I have been so intrigue with the accuracy of my Doxas Mil Ed, and the Searambler after I adjusted them. I knew was missing something. I have adjusted standard eta 2824-2 in the past that they wouldn’t gain a second on the wrist remove the watch from the wrist they go to warp speed, LOL! I wore the Doxa Mil Ed yesterday remove the watch place it faces up it didn’t gain or lose a second over night. Here are pictures from the Dreadnought (TOP) chronometer, and the Doxa Chronometer picture courtesy of Eric. You notice that the balance wheel spoke is flare (Gilt Glucydur), and it has incabloc shock system   Here is a picture of the standard 2824-2, etachoc (novadiac) shock system, with a standard balance wheel straight spoke (gilt nickel) according to ETA chart spec    Elabore movement, same balance wheel as standard accept with incabloc  My point is when you read reviews with the proven 2824-2 movement etc, and buy watches that cost $300.00 and up with the eta 2824-2 I would recommend checking what grade of movement you’re getting for your money they’re not the same. Conclusion: If you bought the Doxa chronometer rest assure that is what you own ( TOP ) chronometer certified COSC, the Elabore Doxa 750t is not a chronometer grade movement, but it’s a Elabore eta 2824-2 with some upgrades from standard. This is just my finding or opinion, if you don’t understand this info I can’t help you.:)

No Sean I don't know, the first four number is the model number of the watch. I been trying to find picture of the movement for while no such luck. I'm quessing that's a standard 2824-2, but not sure without looking at it. :) Nice watch I like it, congrats!hand6.gif

Swiss lever escapement, Incabloc shock absorber, Glucydur balance, Nivarox 1 flat spiral, Antimagnetic, 28´800 vibrations per hour, Nivaflex spring, ball bearing central rotor with heavy metal weight, power reserve to -47h, Etachron fine adjustment, tight tolerance of adjustment Well, the specs for the watch do list it as having an Incabloc shock absorber, Glucydur Balance. So, I would conclude it is the upgraded movement based on your chart and pictures.

The only way to find out for sure is to see the movement.:D That power reserve seem to high for a 2824-2, something is fishy here.

The power reserve is when you fully wind the watch place it on a stationary location without moving it, the watch should stop on or about the amount specified.:P (38 hour later)

>>That power reserve seem to high for a 2824-2, something is fishy here.<< If you go to the German site for Zeno, they claim (to -47h) for most of their 2824-2 movements. I take that to mean (to less than) 47 hours. Whatever, they are consistent. :D:D:D

Highly informative, esp. with the pics. Helped clear up my understanding of the differences between the various 2824 grade's shock absorbers and balance wheels. Thanks Johnny P.

man this is great stuff! i was alway curious about the whole glucydur balance wheel...i know glycine always used them...i once had a beat up very plain looking glycine on the back it said commpressor...it really did'nt look like much but i could'nt believe how accurate it was and the reserve was fantastic! is it the steel they use in these wheels or design or maybe the way they temper them? it seems like this glucydur balance wheel makes noticable difference...even in a cheaper watch...great post

If you read the specs on a Mido it will be much clearer. The amunt of work they do with the -2 is amazing.

All the added modifications, balanced and super nice when running My Tutimas, running a mod 2824 or 2836 really, seems so easy to start from dead, just runs whenicking up and minor shake. Good read Last edited on Fri Aug 23rd, 2013 06:11 am by Tomsimac |

I have a few eta based watches and find my tudor hydronaut the best time keeper, what do tudor do to the movements to make them so good, it also has not been serviced in eight years!

No I'm in agreement the moderfied eta movements in my experience keep perfect time and the standard out of the sealed packet ones also keep good time, in the years I've been collecting watches I've found them better than rolex (except 1520/65) and also the modern patek's, I suppose they have had years to get them perfect.
