·I bought a 2006 model Planet Ocean with 2500C movement back in 2011. It was someone else's daily wear and then became my daily wear until around 2019. It was never serviced for the first 13 years. Accuracy and reliability were great throughout. I ultimately had to get a full service because I dropped it on a tiled floor 😲 My watchmaker charged extra for servicing a co-axial movement, but no major parts needed to be replaced and it's continued to run fine since this time.
