Rock solid Seiko movement although the factory deviation is pretty broad. It’s great that LT regulates them, and it’s well worth the added cost.

Only had it in the new build for a few days, but so far it seems to be sticking within the regulated range.

NH35 Nautilus Build

Bought a regulated NH35 for a new Nautilus build. Movement was delivered swiftly with an uncut stem as well as the shipping/testing stem. Haven’t had a chance to put it on a time grapher yet, but from what I’ve seen after a day of wearing the watch, the movement looks to be pretty spot on.

Amazing service up front.

I’m in the US and my order was in my hands in 5 days. Packaged perfectly. Product was in excellent shape and couldn’t be happier. So ready to build my Nautilus.

My do it all watch

I ordered a GS 39mm case, explorer dial, snowflake hands and the NH35 movement as an fully assembled watch. Communication and follow up was super quick, pleasant and accurate. As was shipping. And the watch is beautiful and even better than expected.

The little touches with the handwritten note, the very secure packaging and the speed of finalising and delivering my order was top notch

Fastest watch parts shipment ever!

I have to say, I've ben modding watches for at least 10 years. 99% of the mod parts are out of Singapore, but to date, this shipment was the fastest by a long shot. So far everything looks good but I won't get to assemble for a few days. Thanks!
