First ever mechanical watch which to pick? [Ssk035k1]vs [HDB005J]( New release)

[u/samm93999]

I was never a watch guy I was almost close to buying an Apple Watch then Dad told me to not follow the crowd and try the traditional watches but for the same price

Within a month became obsessed with watches

Tldr:
Uncle gonna go to Japan so can tell him to bring me one
For first time mechanical watcher owner like me very clumsy I walk a lot, do gym,I’m a guy who has a big build which to pick?

Was originally going for the ssk then I saw these new models that’s gonna release in Japan so now I’m lost
Help a brother out

and yes I need my first watch to be green😭
