44G4JB is not for SKX.
The curvature of the end links fits an SKX but they are not tall enough to cover the space between the lugs.
Secondly, this set of bracelet takes slim spring bars like those on the Seiko FFF models. Fat spring bars will not fit.
I think this 44G4JB is for the slimmer cased 100m divers.
Just to info bros here who are considering this code for their SKX007,009,011,171..... Salah bracelet ah.

anyway if anyone is looking for president bracelet ah goh have a few to sell.
i think have a few as he change some on the 007

For this one you can also take out the clasp from the Seiko FFF / snzf bracelet. Easy job cos the links are flat where they connect to the clasp, using a simple push pin.

Best if you call them up and ask as their stocks varies..

roo, can make this a sticky?

Can add Price to the PN ? <if avail>.
This make it easy for some bro.

does anyone know how much is a Seiko B-21 Calf strap/curved lug end with original deployment buckle?

big-e, i had purchased this strap frm TS before right?

Leather strap black DAE4R - 2100¥. 18mm
DXG7BZ -2100¥ 19mm

Both seem to be the same price, I have not bought this from TS but got it when I got some vintage Seiko (70-80stype) and that's MSRP from a Japanese seller.

21mm curved lug leather strap, PN: 4LJ5KB, for Seiko Premier SLN044 cost S$108.10 w/gst.


The case(SLN044) cost S$288.90 w/gst is unavailable in stock now, if you wish to place an order it takes about 90 days or more from date.

Hey guys, does anyone know where i can get a rubber strap like this? And how much does this deployment clasp cost?

thanks in advance!

There isn't a Seiko technical manual is there? With all the parts catalogued and listed? Like maybe even cross-referenced to the watch?

This would be of great value to a modder... I'm recently trying to get a superdome for my Sumo, but the seller asked that I cross reference it against the part number of the current crystal... pengz...

Dug and dug and finally came across this massive database. It's helped me and I hope it helps you too!
