Siduna as a watch brand presently comprises of only one single watch model in two development varieties. That’s a sorry brand one would say. Be that as it may, Siduna has plans for more and, despite the fact that I had never known about it, it isn’t another watch brand at all.

Siduna M3440 Professional Flyback Chronograph

What was before the Siduna M3440

In the last part of the 1800s effectively, the Siduna brand was established in Bienne, Switzerland, and got known as a maker of forcefully valued pocket watches. Afterward, in 1929 to be exact, the company was moved to Denmark and turned into a provider of essentially 18k gold chronographs. In the same way as other watch brands, Siduna didn’t endure the seventies quartz-emergency. At that point, in the second 50% of 2000, a watchmaker from Stockholm purchased the brand name and utilized it broadly till his retirement in 2016. He at that point offered it in 2017 to the current owner Francis Jacquerye, who chose to resuscitate the brand along with Swedish, Bordensber and Wostep ensured, watchmaker Peter Wadbro.

Francis Jacquerye has just been in the watch business for more than 15 years. After examining Industrial Design, he worked in Italy, where he prepared as a goldsmith. He at that point found a new line of work with Longines in Switzerland and was elevated to plan administrator in 2011. By 2016 he moved to Sweden and, along with his better half Anna, established . A company offering, technique, plan, and excellent assembling of extravagance watches. Googling Francis Jacquerye will instruct you that he is one of ‘s top contributor’s in  analysis, procedure & cost optimization 

Frankly, learning of Francis’ high premium in examining system and cost advancement made me look much nearer at the Siduna M3440. Is this watch simply a showcasing stunt? My decision immediately is: on the off chance that it is I couldn’t find it.

What was the motivation for the Siduna M3440?

That doesn’t mean I couldn’t discover showcasing driven decisions, obviously, however nothing amiss with that. For example, I scarcely could discover an association among Siduna and the famous Viggen-scratched Lemania military chronograph it’s got from. But likely that the brand Siduna was known to create chronographs in the past also. Also, that the brand as of now lives in Sweden while the Lemania Viggen was utilized by the Swedish Air Force.

As such, the Lemania chronograph wasn’t selective to the Lemania brand around then. Planned by Ervin Piquerez in 1968, a similar case was utilized by brands like Breguet, Bucherer, Heuer, Sinn, and more. Francis utilized his experience from Longines tests at recreating memorable watches with present day materials to plan the components and pick satisfactory providers. Up to 75% from the Siduna M3440’s parts come from mainland Europe. In 2018 Siduna collected the pre-arrangement of the Siduna M3440 watches, from which we have one for survey now.

First impressions

It’s quickly evident that we’re taking a gander at an actually excellent item here. Delightful matt dark dial with recessed auxiliary dials, high difference numerals, records, and hands. Really substantial (106 gr), with an outrageous pleasantly completed case, and fitted on a thick full grain calfskin tie. The last in Havanna-earthy colored is absolutely my favored choice. The watch’ determinations are largely on par also. 10 bar pressure tried 316L case, marginally domed sapphire gem, and wearing a reliable caliber got from the great Valjoux 7750. For this situation, outfitted with a Flyback construction.

The confirmation is dealt with too. Hostile to Magnetic as indicated by ISO 764, Shock-Resistant to ISO 1413, and Water-Resistant to ISO 22810. What I miss here is meeting to any flight instrument rules, similar to DIN 8330. I’ll momentarily get to this later.

A uni-directional pivoting bezel?

The pivoting bezel is something promptly standing out too. While breadths of watch housings and bezels are frequently pretty much equivalent, the bezel of the Siduna M3440 sticks out. With an estimating measure close by, the breadth of the packaging is 39,6 mm while the bezel is 42 mm.

And when pulled in to it, the following thing, obviously, is turning it. In spite of the fact that feeling exceptionally strong, I was shocked to discover that it’s uni-directional turning (regularly this will be the situation by diver’s watches). I would say and as far as anyone is concerned pilot’s chronographs ordinarily utilize bi-directional bezels. The Lemania Viggen, where the Siduna M3440 has gotten from, had a bi-directional turning bezel too. It may even be that DIN 8330 for Flight Instruments requires it, and this is one reason the Siduna doesn’t comply.

Not complying to DIN 8330 isn’t something to keep in touch with home about coincidentally. At present, just a few brands supply pilot’s watches which meet this standard.

An great height

Because the distance across of the Siduna M3440 is very moderate, the stature flaunts amazingly. No under 16,1 mm. Along with the shape and shade of the bezel, I need to say that this makes the watch rather cumbersome. Albeit the packaging configuration was gotten from the one made by Ervin Piquerez in 1968, there are some noteworthy contrasts. On account of the utilization of a programmed chronograph development, it needed to fill in tallness. Among different spots, this is gotten by expanding the stature of the lower part of the bezel essentially. By this, the extent proportion of the packaging got somewhat annihilated, in my opinion.

A wonderful yet sadly uncomfortable strap

I can envision that you don’t need to fit a watch of this stature with a dainty lash. That would emphasize the stature of the packaging significantly more and wouldn’t look wonderful too. So Siduna decided for a top notch significant German calfskin tie, as said in Havanna-earthy colored on the watch we got for review.

As it’s an excellent lash and looks great on the watch, I attempted to wear it for certain days. With its thickness of no under 7 mm, it didn’t break in however and remained excessively hardened for comfort. The watch was sitting high over my wrist and went to one or the other side of my wrist. I needed to discover another answer for wear it, as this didn’t do it justice.

Dodane, Sinn and Zenith. Comparing the M3440

As referenced, many watch brands used to supply this kind of pilot’s chronograph. Many actually do. It’s evident that the Siduna M3440 is certifiably not a selective appearance. Equivalent looking watches which come to my psyche are, for example, the Dodane Type 23, the Sinn 103.Ti.IFR and the Zenith Tipo CP-2. Where the Zenith – principally due to its development I surmise – with a cost of € 7.900,= is in an alternate class, the Dodane and Sinn pretty much aren’t. Both, notwithstanding, have a higher rundown cost than the Siduna M3440. Comparing the no-Flyback renditions (as the Sinn isn’t accessible in Flyback) the value range resembles this: Dodane Type 23 € 2.900,= – Sinn Sinn 103.Ti.IFR € 2.440,= – Siduna M3440 € 1.850,=

Conclusion and specifications

The Siduna M3440 is an excellent and top notch chronograph. Despite the fact that it can appear to be somewhat cumbersome, it looks great from each point. Furthermore, it has its specialized particulars just as its development right. Wearing the watch on my 18 cm wrist, tragically, was a to some degree distinctive experience. The lash was excessively thick and too firm to even think about getting around my wrist comfortably. An alternate, gentler and more slender, tie got the job done. In any case, it should be said; it didn’t look as great as the first one.

And then there’s this. The Siduna M3440 isn’t a sub-€ 500,= modest beginning up miniature brand watch. The cost of the watch we’re inspecting here is € 2.350,=. That’s cash which gets you a watch from since quite a while ago settled brands too. In this value association, one purchases a watch which ideally can be worn for quite a long time. What occurs on the off chance that I need another crown, pushers, hands, or even a dial, in, let’s say, a long time from now? Can Siduna actually supply that? Purchasing an item from a new business in this value alliance, I couldn’t want anything more than to get a smidgen more certainty, which ought to guarantee the accessibility of extra parts for a more extended period of time.

Please note

We need to comprehend that the watch we’re inspecting in this article is a ‘press sample’. I’m not certain if this implies that additional consideration has been taken to make it great 😉 However, I surmise this implies that it’s still a model and it very well may be conceivable that a few subtleties will improve. From my perspective,  a bi-directional bezel and a more comfortable lash would be welcome alterations.
