I surely am into Apple Watches, got like 30 og bands 🫣 I bought a S5 ceramic on ebay for 450$, looks like its in mint condition, apart from the battery, which will be another 100$ i think. I‘ll keep you updated - I am very excited to have a completely white work attire🤩
Get the battery (watch, that is) replaced ASAP, assuming it is below the 80% threshold. No one knows when Apple will mark the S5 as obsolete.
