Festina f16561 yr 2010 meets new strap!
Not only this is my favorite Chrono from Festina, it was purchased in France, carrying many memories. Now refreshed with the better than the original blueish strap, becoming a bright yellow touch, instantly recognized, wherever I wear it. Looks like I‘ve got the last available strap. That makes it even more fancy! Lucky I am!

Very happy now
Had trouble getting the item the first time. The dial was returned to holland and had to be shipped out again. BUT they were very communicative and allowed me to add a second hand to the order that was out of stock for my first order. Very pleased. Amazing product, my first real seiko dial!

Fast shipping and great quality
The shroud took a little bit over a week to arrive, but it was pretty quick considering that I live in Australia, it came perfectly secured inside the packaging with the original Seiko part number label, super easy to replace and great quality. I hope that they stock them again soon to buy another one just in case I need it in the future.

Couldn’t do it without them!
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.

Certain Parts for 7549
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
