Comparison of Rolex Deepsea , Omega PO and Seiko M 

The reason the PO has a less smooth sweep is because when they add the coaxial escapement they slow the movement down from 28000bph to 25000bph

Watch Straps seiko ???? thanks ... link ?

is the PO a 45mm?

I had a Deep Sea for 6 years until their acclaimed COSC-certified movement crapped out and had to be "maintained" by Rolex to the tune of 1K every 5 years apparently. After selling it and upon further research, I found out that COSC accuracy is eclipsed by the Grand Seiko Standard and the GSS 8L55/9S28 hi-beat movement kicks the crapola out of anything that Rolex produces. In fact, my current Marinemaster 1000m Ti 36000 Hi-Beat 50th Anniversary Edition completely blasts the Deep Sea outta the water! No comp whatsoever!

Seiko , lume kings

I have one question and one comment: is that the same Sumo as the one in your Sumo/MM300 comparison video from February of 2016? I didn't notice any scratches on the case or crystal in this video which were very obvious in the February video. I hope you were able to return the watch to the crook who sold it to you and managed to get a nicer one. My comment is about the crown on the Rolex. You mentioned that it had just come back from a full service. This might well explain the fact that you could not get the crown positioned upright when you locked it down. My guess is that whoever reassembled the watch after its service reattached the crown stem in the wrong position, causing it to not lock down in the right position.

I absolutely cringed when you basically dropped 3 of the 4 watches onto the cement... Yikes!

Four very good and very exciting watches . One bloody boring so called " reviewer ". It might be better if you say NOTHING !
