Gold cases, Spring bars and servicing

Having taken ownership of a lovely Longines ultra chron, I was hoping to get some advice on bands. I'm sure I read somewhere that Spring bars can damage the case. If so, is there a better alternative?

Also, having never owned a vintage watch, I'm keen to make sure it's treated well and I was hoping for some recommendations on where to get it serviced (I'm in the UK)...

Any thoughts welcome!

Thanks in advance

Spring bars will not damage the case. An inexperienced person trying to take out or put in spring bars will or at least can.

As long as you follow certain precautions, you'll be fine.

Thanks for the responses. I get it - it's not the use of spring bars themselves, it's the taking them in and out. I think you're right @gatorcpa - I was reading some comments on another watch that someone had posted and one of the comments read along the lines of get that strap off the watch asap.

And yes, it is indeed the watch you've posted above - genuinely, it looks awesome! I've already bought a dark brown band. I think I've mentioned a few times, but it's for my dad. I've also bought a (modern) Longines matchbox and I'm having a brass plaque engraved to place on the inside. I think he's going to be thrilled!
