… and you visit a Grand Seiko Boutique with no intention to buy a watch!)

Hello dear friends!

As we have told in previous post Art and me visited NY Grand Seiko Boutique during our past great GTG a couple of weeks ago.

Both Art and me entered the shop with no intention of buying any watch (I say it honestly!) but you already know Art fell in instant love with the Night Birch.

Now while he was dealing with his watch I browsed the many displays there and discovered the “Blue Birch” cousin of Art’s watch: SLGW 007.

This manual wind watch is powered by the beautiful caliber 9SA4 high beat, 80 hours power reserve.

Its dial blue texture is said to evoque the moonlit birch tree and it looks so nice that my horological heart begun beating fast and loud.

Well… as it happened to Art, I fell immediately in love with it.

But as I had a friend at the Miami Boutique I preferred to get it there after my return to Miami.

I phoned my friend in Miami to be sure they had the watch in stock and asked to reserve it till my return from Atlanta after the Knife Show.

Yesterday I visited the Miami Boutique and finally got my watch.

This watch will be a very special piece in my collection which will remind me of a great time spent with our friends assisting to the NY GTG, the nice two days spent in NY with my dear friend Art and our little adventure visiting the Grand Seiko Boutique with no buying intentions.

Key Points from the Discussion

The SLGW007 shares its exceptional manual-wind Caliber 9SA4 movement with the SLGW005, a detail appreciated for its high beat rate, 80-hour power reserve, and the tactile pleasure of its winding action.
The 'Blue Birch' dial of the SLGW007 is particularly striking, with its texture designed to evoke a moonlit birch tree, a testament to Grand Seiko's renowned dial artistry.
Many collectors, including RDSChicago with his SBGY009, express a strong preference for manual-wind movements, valuing the direct interaction and the aesthetic appeal of such calibers.
The thread highlights the strong community aspect of watch collecting, where shared experiences like GTGs (Get-Togethers) and boutique visits often lead to memorable acquisitions and 'friendship watches'.
The SLGW007's manual-wind movement is praised not only for its technical specifications but also for the enhanced sound and feel of its winding action, providing a special sensation to the wearer.
The discussion draws a comparison between the SLGW007 and the SLGW005, noting they share the same movement but feature different case aesthetics, with the SLGW005 utilizing a 45GS case design.

The WristScan team is propping up Japan's economy! . . .

. . . Kristjan is also a Seiko fan - I wonder if he's considering a GS anytime soon. Then we would be the GS Trio! Emmanuel's GS shares the movement of yours, Abel . . . you know what they say, "Great minds think alike." 😇

Ha ha ha!! Yes, the GS trio! Lol!

Yes, I know about the old saying!! 😂😂😂 Good to know Emmanuel GS has same movement. I love the looks of the movement and the little but nice detail of the small hand power reserve it features. Also like the designers enhanced the sound and feeling of the winding action. It gives a very special sensation when winding. I wish you are enjoying your new GS so much dear Art! Now we have two Friendship watches!! Cheers! Abel Cheers! Abel
