Heimdallr Monster | Excellent quality & Low price | Why it's still underrated?? 

I got the textured blue dial one and a Sea Knight orange monster that looks the same and was quite a bit cheaper. I was underwhelmed by the textured dial one, so I have not opened and put it up for sale. I like the orange one. I had the 1st gen seiko orange monster. The Seiko had a lighter shade of orang, the sea knight is a little darker and slightly more red shade of orange. The Seiko, which I sold years ago, I remember having a smoother bezel and did not have those sharp corners on the shroud/case that I feel when turning the bezel. Overall I am happy of the orange Sea Knight. Seems accurate and looks good. I am tempted of removing the bezel and file or sandpaper those sharp corners. Of the ones you showed I like the dark blue the best. Nice to see them in video here, gives amore accurate idea than the renderings on AliExpress. I like the white textured dial better than the blue. But the current seiko monster has a nicer textured dial, the save the ocean one. But it has a Hardex crystal, a magnifier cyclops that I do not like, and is a lot more expensive.

It’s a bit chonky love that the indices look like teeth, it’s a bit like the Kamasu

Tandorio also had one

Steeldive makes one as well...

heimdallr is the same price as seestern , I prefer seestern Monster.
