Due to its absence from any watch fair, certain timepieces, like the Longines Hydroconquest GMT, often remain underappreciated. Released last year in a 41mm case, it appears here in a larger 43mm size; Longines stands out as one of the few brands opting for larger sizes in 2024, which adds importance to this unique dive and GMT watch combination. Furthermore, Longines offers a newer GMT model in the Spirit collection, and while this Hydroconquest utilizes a similar movement, it carries a slightly different designation. Both the 41mm and 43mm models feature the same automatic calibre L844.5, whereas the Spirit Zulu Time is equipped with calibre L844.4. As of now, additional technical information regarding these calibres is not available. We previously encountered both the Spirit Zulu and the 41mm Hydroconquest during their model launch last year.
In any case, the enlarged Hydroconquest GMT is largely identical to its 2023 counterpart, apart from its size. This maintains a water resistance rating of 300m, suggesting that the increase in size may simply be a response to consumer demands. We have yet to physically compare both models, but all the features listed, including the contrasting satin and polished finishes, remain consistent. However, when reviewing the specifications and descriptions, it seems the 43mm variant does not include gilt or silvered hands and hour markers, although the SuperLuminova application is unchanged.
Typically, we don’t mention pricing at the start of discussions, but both models are shown on the Longines website and here, too, we see parallels. In fact, the price point for the 41mm and 43mm models is nearly identical, although the larger version lacks a Nato strap alternative for comparison (we are focusing on the bracelet, which is the most expensive option, and both models share this feature). For more information, consult your authorized dealer or boutique.
Examining the specifics, there is no brown dial option for the 43mm model; available dials include black, blue, or green. The crown guards maintain the same shape across both sizes; this design element distinguishes it from the conventional Hydroconquest model, as confirmed by Robin Nooy from Monochrome. Since we did not discuss calibre L844.5 upon its introduction, we will summarize with some specifications. The balance spring is made from silicon, while other (unspecified, but typically part of the escapement) components are crafted from non-magnetic materials. Once again, these specifics are not detailed.
