First time buying from GeekTime – Cartier Santos

Hi everyone,
I’m planning to buy my first replica watch from GeekTime, specifically a Cartier Santos.
I just want to make sure I’m dealing with the correct contact before sending any money.
Is this Telegram number/contact for GeekTime legitimate?
Telegram: +852 5 574 2295
Is paying by Revolut transfer generally safe?
The seller told me the whole process will take around 5 weeks. Is that a normal timeframe?
Is there anything else I should know or check before placing my first order?
I’d really appreciate any advice from people who have ordered from GeekTime before.
Thanks!
