Jrwong23's return to the forum highlights the Grand Seiko SLGW005, a modern reinterpretation of the iconic 45GS. This post provides a collector's perspective on its design, the impressive 9SA4 movement, and its versatility, offering insights into why this particular reference has resonated strongly within the community.

Hi everyone, I haven’t posted for a loooooooong time!
Glad to be back this weekend smile

In recent months, I got “rebitten” by the GS bug. Sharing a belated incoming post. I got this GS SLGW005 in Dec 2024, the remake of the legendary 45GS. This is a home run for Grand Seiko last year ! An early Christmas present for myself and just in time for my vacation last Dec to Osaka and Kyoto.

Other than the beautiful and technically impressive hibeat manual winding 9SA4 movement, the 45GS case is really iconic and just looks so good ! The off white dial is also very Japanese. And this watch is such a strap monster too - I don’t really like the black leather strap that comes with the watch and it easier pairs up with various calf leather and rubber straps I have. Sharing some pics below.

Have a great weekend everyone ! I hope to post here more often from time to time instead of just lurking around. 

Cheers!
Robin

About the Grand Seiko Heritage Collection Ref. SLGW005

The Grand Seiko SLGW005 is a limited-edition model within the Heritage Collection, designed as a recreation of the 45GS. This reference is notable for its distinct case design and the integration of a modern high-beat manual-wind movement, distinguishing it from other contemporary Grand Seiko offerings. It represents a specific aesthetic and technical direction within the brand's historical reinterpretations, focusing on a more traditional, dress-oriented profile.

This timepiece features a stainless steel case, measuring 38mm in diameter and 10.3mm in thickness, with a box-shaped sapphire crystal. It houses the manual-wind Caliber 9SA4, which operates at a high frequency and provides a power reserve of approximately 80 hours. The movement is visible through a sapphire exhibition case back, allowing appreciation of its finishing and construction. The water resistance is rated at 30 meters.

Appealing to collectors who value historical fidelity combined with advanced horological mechanics, the SLGW005 offers a refined alternative to Grand Seiko's more sport-oriented or larger-cased models. Its limited production and use of stainless steel position it as a significant piece for enthusiasts of the brand's heritage and high-end craftsmanship. The dial color is a subtle silver, complementing the stainless steel case.

At the same time I got this SLGW005. Both are nice but I chose the iconic 45GS remake . With limited budget, I couldn’t choose both! But when I saw these autumn scenes in Japan, I did think of the SBGY035 again lol
