Ulysses Investigates the Seiko NH36 Movement

I told Ulysses I bought a Deep Blue watch equipped with a Seiko NH36 movement. Ulysses wrote:

I checked it out; it appears to be a Chinese-built version of the 4RXX movements. Accuracy looks poor but i'm sure it's a solid movement otherwise. The 4RXX movements are already considered cut-down and can be found in various Seiko 5s, so i'm guessing the choice of the NH36 is primarily for cost reasons.

I bought the DB Aqua Pro 1500 last spring. Out of the box, it lost more than 10 sec per day: 5 min/month is my limit. It remained like that for days, and I returned it.

Barney, that makes sense since the movement in that Deep Blue model is the cheaper made in China Seiko movement. I sold my Deep Blue with the same movement and based on what you said I would not buy that movement again. Thanks.
