Yes this is an homage of famous Seiko SKX007, which is also known to be discontinued (although it was so popular that its stocks in any country won't run out soon).
But this one from HEIMDALLR is better than the original SKX in every single way! While Seiko SKX007 has Hardlex crystal, non-hacking 7s26, and Aluminium bezel, Heimdallr's counterpart has Sapphire crystal, hacking NH36A, and Ceramic bezel. And also it is more affordable.
