Looking for any info on Constellation - F300Hz

[bronco1626]

I have the opportunity to buy a Lapis Lazuli Constellation - F300Hz ref 198.0034 (not the specific one pictured).
I read online broadly about the F300Hz series of watches and how they're a pain in the behind to repair, and that watch makers who have the skill to repair this series are few and far between. Moreover, I just can't find historical information on this specific model.

I like it a lot! I love that Omega has incorporated one of my favorite precious stones into one for their watches, but I just don't know if it is a good idea to buy the watch if keeping it operational is going to be such a heart ache. Anyone have more insight or experience with this series of watches?

I have two f300 watches.

Both run well but I initially had problems sourcing and fitting a battery on the Connie I bought on OF Private Sales (but now all sorted) and I made a mess of setting and changing the date on the Geneve I bought on eBay but had it serviced by the Croydon Service Centre (£300) but it runs great now).
