6 month Omega dial Cracked

Bought my Omega seamaster 300M diver watch last July and I just noticed the dial has cracked. I have babied the watch and has no impacts at all. Yet 2 days ago I noticed the dial has a crack. Has anyone experienced this? I’m currently travelling and wanted to get it fixed while im in Dubai using warranty. Has anyone experienced warranty replacements and how long it takes?
Any help would be appreciated.
