Original part, already oiled and timed.

part fits ok, fast delivery, good service, always recommended, thank you!

I have replace the seiko 6r15c with this movement and now with watch works

Great service and fast turnaround. However, I had hoped to modify this movement by adding the day wheel complication. However, the post for the day wheel is missing - although the bore hole for it exists. That is a bummer as I now have to engage a much more substantial rebuild, using the base plate of an NH36. Oh well, I guess I will learn a lot, treading on uncharted territory.

Perfectly packed.

This 6R15 so far, is an excellent movement. Purchased this for a watch build I was working on and am very satisfied. Do note that the 6R15D movement (specifically the D model) does not have the post on the main plate that holds the intermediate wheel required for installing a functional day wheel. If you're doing a direct swap from a 6R15 then this is no problem, but if you're trying to add a day wheel some additional modification may be necessary. Otherwise, out of the package this was running ~+15s/day after two weeks, and I've since regulated it in to ~+2s/day. Couldn't be happier. Quick shipping, well packaged products, great prices, and tons of OEM parts, what more could you ask for.

The part was of great quality and service thank you ..

item works well, keeping time to within -5 secs per day.

great customer service from you folks. thanks
