Introducing the M3440 Professional Uni-Compax Chronograph from Swedish Brand, Siduna

Introducing the M3440 Professional Uni-Compax Chronograph from Swedish Brand, Siduna


At times I see a recognition watch and mourn, “Yet another copy.” But there is now and again a story behind a watch that makes a tribute—or praise, reissue, diversion, or whatever we choose to call it—special. The restricted version 42-millimeter, Valjoux 7750-prepared M3440 Professional Uni-compax Chronograph from Sweden’s Siduna may look almost indistinguishable from other mid-century pilot chronographs, yet its story is remarkably Swedish and rather compelling.

By the last part of the 1930s, Sweden had a careless military, was desperately dispossessed of fuel, and wound up encompassed on all sides by Nazi-vanquished nations. To avert a Nazi assault, Sweden deliberately gave iron to the Nazi’s, a reality that uncovers the risky complexity (difficulty, truly) of remaining “neutral” during wartime. Not having any desire to get captured ill-equipped once more, Sweden whimsically redirected most of its Cold War atomic weapons financial plan into its airborne abilities. Astoundingly, by 1968 Sweden promoted the world’s fourth most remarkable Air Force. The Siduna M3440 is an amusement of the 1973 chronograph (nicknamed “Viggen” after a Swedish warrior fly) gave to that quickly growing Air Force, or Svenska Flygvapnet.

Siduna is offering the M3440 as both a standard 7750 chronograph (1,860 Euros) or as an altered 7750-based flyback (add 480 Euros). The case is produced using treated steel, and the brushed surfaces (with some discrete mid-case cleaning along the sloped drags) and natural structure factor declare the M3440’s mid-century pilot watch pedigree.

Other than the Siduna name under 12-o’clock, there’s nothing we haven’t seen previously while exploring this well known kind. A 42-millimeter measurement case with a husky 16.1-millimeter thickness is finished off with a standard hour long pivoting bezel around a twofold domed sapphire gem with hostile to intelligent covering within. An independently numbered strong screw-down case back gives 100-meters of water opposition. The dial is matte dark with recessed sub dials, and the five-minute lists, numerals, hands, and bezel markings are totally covered with C3 Super-LumiNova. Cleaned siphon pushers and brushed crown are the place where every one of the 7750 pushers and crowns go.

Three cushioned calfskin ties are accessible in dark, dull earthy colored (havana), or tan (rouille), each with grayish sewing. The pin clasp is marked and delivered in coordinating hardened steel. To some degree confusingly, one should add the cost of the lash ($40) to the expense of the watch, or, I assume, do without getting it (maybe not the most exceedingly terrible alternative for those of us with boxes of ties laying around). Lash width is 20-millimeters at the spring bars with a delicate shape across the cushioned section.

Pre-request is currently open for the Siduna M3440 with your decision of chronic number, except if you need numbers 001 to 010, 019, 080, 088, or 099, which are being unloaded off.  Siduna
