126618LB vs 116618LB

[Jeevesbond]

Hi folks. Really want a full gold sub bluesy. I have been considering trading a tt sub 126613LN for one of these. I have found an older 116618LB and am trying to understand any large differences against going in for a trade against this (much cheaper) vs a newer 126618LB. Anyone with both can comment? Also the older one is from 2015 and newer one is 2023 so warranty is an issue. Anyone know what a service runs on a sub gold bluesy and can help make a decision between these. Again the price difference is substantial (around 7k) and im trying to decide if it is “worth it.”

Some
Differences i saw were updated movement, slight case design differences to 41mm improving proportions, longer power reserve to 70hrs (i rotate watches so this doesnt bother me much as i wear a few weeks in a row then wear something else) and maybe gold lettering vs white. Also crown between swiss made. Ive heard bracelets are different. Anything else im missing?
