Seiko SRP637 Extension Link 4R36-03Z0 Baby Tuna

Good genuine product

Tuyệt vời

So I like to mess with beat up watches found on various auction sites. They are often sad and neglected pieces therefore I have several ‘go to’ suppliers that have the hard to find NOS items required to bring the watches back to life. The pic shows all those a bunch of Seiko’s that I’ve found over the last few months that have needed saving … I couldn’t have done this without the input from Watch Plazza. The Pepsi BFK is the one that this bezel was purchased for.

High quality oem dial

My old Seiko tuna 7549 from 1981 needed some love instantly . By missing of Original 7549 parts
I ordered in this shop :
Hand Set for sbbn015
Double Dome hardlex
Glass gasket
Kanji day Wheel for 7c46

With those original parts the 7549 was replaced and improved by an 7c46

Good to have trustful Shops like watchplaza to bring my old tuna back to modern Standard

Cool looking dial. Will definitely order again soon! 🤗

I like this pink matted Apple watchband very much. Glad that I bought STRPZ

This magnetic apple strap made of silicon is high quality. I would recommend it.

High quality and fast shipping!

The quality is better than what I bought before. The seller is highly recommended. The workmanship is +

Watch Plaza offer the seemingly unbuyable - replacement rubber straps for Seiko Arctura watches. Thank you WP - I'm enjoying my watch again, the strap fits and works perfectly - 😀

I bought this black leather strap with red stitching as a compatible replacement for my Seiko SNL021. The genuine leather felt comfortable from day one and softened nicely after a couple of wears. Stitching is tidy, and the subtle red detail picks up the chronograph accents without shouting for attention.

Fit and finish are exactly what I hoped for. The watch sits neatly on the wrist and feels refreshed—ideal if your original band is tired. At this price, the value is strong. It’s not an original Seiko part, but the quality feels solid and it looks right at home on the SNL series.

Pros

- Genuine leather; comfortable for daily wear
- Clean look: black with red stitching
- Good value at the current price
- Clearly labelled as compatible with Seiko SNL029, SNL021 and SNL017

Cons
- Needed a short break-in period (a day or two)

If you’re after a Seiko SNL029 strap or SNL017 watch band in this colourway, this compatible replacement does the job gracefully.

Top quality and fast shipping!

Hard to find this part, but luckily they have it in stock

Quality oem dials as usual 👌
