What movements have surprised you in terms of accuracy?

[CashEnthusiast]

When I first purchased my Sinn U1, there was no chance in hell I expected it to be the most accurate watch in my collection. Boasting a Sellita-200, I expected the ETA clone to be inferior and no where near as accurate as it turned out to be. Compared to my Breitling, Tudor, and Rolex movements, this Sellita movement has been a rock steady +1/2 sec/day (if that) for 25 days and counting.

A welcomed and pleasant surprise. Would be interested to hear some of yours.

I recently put most of my watches through COSC testing and was surprised in particular by my miyota 8xxx watches (the Aevig and the Shi Chen, which only stopped because I didn't winds it enough) as well as the citizen cosmotron 7803a pieces.

Longines Flaghship Heritage. I just posted this as an update to a thread i posted a few years ago, but i'll post it here too. In fact, all of my swatch group watches have been very accurate. Omega sea master professional 300m, tissot le locle, and longines flagship have all kept an average time of less than 1 second per day. My omega seamaster pro 300m chrono kept about 2 seconds per day. These charts are for the longines flagship heritage for the last 6 months. The excel table is of the last 180 days, the chart is of the last approximately 250 days.

I can't say I was surprised, since I didn't expect Sellita movements to be inferior. I have four watches with Sellita 200-1 movements and the LEAST accurate is +4 spd. None are COSC certified.

I knew Rolexes are well adjusted, but my SubC still surprised me. After 110 days measuring period the fastest rate has been +0,6 sec/day, slowest -1,3 secs and average -0,4 secs/day.

Could have gone another three months without setting it, but travelling to another timezone interrupted my test.

Pretty chuffed with the movement in my Daytona.
