Longines revealed its Twenty-Four Hours (ref. L2.751.4.53.4) “aviator” during the Baselworld 2011 show.
Featuring everything a die-hard fan of vintage style could hope for (well, perhaps sans the movement since the new version comes powered by a modern self-winding mechanism), the new timekeeper is a good example of a “vintage-modern” pilot’s watch that successfully combines historic styling with reliability and ease of use provided by modern technology.
Longines Twenty-Four Hours: First Impressions
2011 was a year of remakes. During both SIHH and Baselworld shows, many brands, Longines included, presented several collections that were inspired by their own watches from 1930s to 1950s.
This Longines Twenty-Four Hours, for example, is essentially a slightly face-lifted reproduction of the 1950’s Longines three-hander that was ordered by the Swiss national airline, Swissair, for its pilots. There were some subtle (and some not, see below) changes to the timekeeper’s dial and the movement behind it, but, all things considered, this a great take on a classic “aviator” watch from days long gone.
The Dial
Compared to the original, the remake now features a date aperture and a more contrast dial layout. The three hands are made of plain stainless steel, while the “historic” version featured hands made of gold: a material that is less prone to oxidation and, as the saying goes, better stands the test of time.
The onion-shaped winding crown is also a trifle larger.
The signature 24-hour scale is still in its place, though.
All Arabic numerals including the smaller ones on the railway-style minute track are printed with bright Superluminova that, together with thin strips of the same luminous compound on the hours and minutes hands, ensures adequate readability even if the lighting is not very good.
Of course, the 24-hour display may be a bit hard to read at first, but, I am positive, you will get used to it in no time.
The 47mm Case
Sort of predictably, the Twenty-Four Hours will be sold in an oversized stainless steel case 47.50 mm in diameter.
While these photos sadly don’t give you an idea of how big this timepiece is, trust me: it is huge. Even despite its relatively short lugs, the watch will happily occupy your whole wrist (and then some, if you are one of those skinny types that are particularly interested in all things vintage if you know what I mean).
However, if you are ready to sacrifice all the living space on your wrist, you will not be disappointed with this little steel monster since all elements look proportional to each other and are also nicely finished, although some may find the large crown a bit uncomfortable even despite its ergonomic shape.
Besides a normal for this class of timekeepers sapphire crystal with double anti-reflective coating, there is also an engraved “hunter” back cover that protects the sapphire display back.
Although I don’t see much practical value in this element, it still looks extremely cool.
The Modern Movement: Longines L704.2
Opened with a small pusher located at 4 o’clock, the cover then provides a superb view of the Longines L704.2 automatic movement, which is based on the Valgranges A07-171 ebauche.
Introduced about five or six years ago as a response to the growing popularity of oversized mechanical watches, this member of ETA’s Mecaline family the Valgranges A07 is a larger version of the legendary ETA 7750 family.
Although the line proved to be not terribly popular among independents due to the initial set of problems that plagued them at the start, as well as a high price tag that ETA sticks on them, I must assure you that updated versions of these mechanisms are both reliable and good at keeping time.
Availability & Price
Given the quality of movement that powers the L2.751.4.53.4, its MSRP of approximately $3300 (depends on the market, as usual) doesn’t seem to be too high, although I would have waited a bit before these devices appeared in online stores to save at least 25 percent of its price.
