New Seiko Luxe SPB377 On Timegrapher

Man, I recently acquired the very same time grapher. This will only serve to fuel the massive fire that is my love of documenting watch specs and building up of tables/spreadsheets.

Yep, I have a pretty detailed spreadsheet on all my watches.

Thanks for posting!

I’d say crown down the most common position through my normal day. Does the timegrapher mesh with your experience wearing it in daily wear?

Generally speaking, yes. My most precise watches, such as the COSC certified Breitling Premier B09, also do fantastically well on the timegrapher.

Share the data results!!!

I’d love to learn more about what you track!

I meant more the results you are finding from data sets. Sorry for not being clear. Wasn’t sure if your data was telling you anything or just you like the tracking for fun. Great either way.

Hmm, for me I am merely curious about the performance of individual watches, and I have only managed to get into this with 5 of my watches, all of which have differing movements.

To your question, I believe a "data set" consists of a large(ish) pool of data sourced from similar or the same type of movement; for instance, if I have data from at least 50 watches with ETA 2824-2 / SW-200 / Soprod P024 movements.

Sadly, I'm in no position to provide this "large data set", but I'm happy to share what I have found thus far from the few watches I have tested 😊

This is great. I haven’t dove into movement accuracy tracking yet. This gives me an idea of what others are doing. Thank you.

I have the JDM green dial version of the same watch. I don’t have a time grapher but it runs about +25 secs a day ( as per my primitive measurements)

Honestly, the main reason I got into this is because I read that you can get an idea of how healthy a movement is by measuring its amplitude. When it drops too low, it's time to send it in.

I'm just happy that I don't own a Timegrapher...🤷🏼‍♂️😄
