Omega Speedmaster Professional
I have a Ludwig 35 and a Tangente 38, both manual winds purchased from ADs in the last 8 months.
- The Ludwig was +6 spd at full wind and +13spd after about 8 hours. I took it to a trusted local watchmaker. Waiting for it to return.
- The Tangente is +6 spd for the 24 hrs till the next wind.
I wrote to the Nomos Service Department, and they said the watches are not chronometers, and that if they are within 1 to 2 minutes per week (~8 to 17 spd), then they are within spec. I love these watches, but I have to admit, I was a little disappointed. Most of my manuals run better than this. I'm thinking of a Tangente 35, but first want to see what my watchmaker can do.
An update on the accuracy of my Tangente 38 Date:
First ten days of ownership: Averaged -4.0 spd
Days 11-20: Averaged -1.9 spd
Days 21-31: Averaged +0.5 spd
Days 32-37: Averaged +0.2 spd
Overall average over 37 days: -1.4 spd
I wanted to ask everyone what they think of this. My Tangente 38 Date (caliber DUW 4101) is trending slower and slower with each passing week and I have no idea why this might be happening. Please see the following data from timing runs between January 6 and April 20:
I wind the watch every morning, wear it all day, and leave it dial-side facing up on a table while sleeping.
Does anyone have insight as to why the watch has consistently lost time, and has consistently lost more and more time over the past few months? Has anyone else with a DUW 4101 noticed similar accuracy issues?
Finally, is this something I should mention to my AD on my next visit?
I don't have a way (that I know of) to measure the amplitude at home. I just have a pretty straightforward timing app on my phone. Any suggestions?
Thanks for the quick advice, Mike!
I thought I'd give an update on the Nomos: I brought it into my AD yesterday and they told me they, too, suspect an amplitude problem. They are sending it to Nomos (their New York location) for diagnosis and repair, and it will be 5-6 weeks before I have the watch back. They said Nomos would disassemble, inspect, and re-build the watch from scratch, and I'd essentially be getting a "new" watch back from them.
Good thing it's under warranty! :P
PS While I was there, my AD was very gracious and showed me the Lange Saxonia I'd been obsessing over pictures and YouTube videos of. Yeah... I'm gonna have to get one of those one day. Pictures, videos, and words don't even come close to doing justice to the beauty of this watch.
