Sinn 556

Sinn 556 I

The watch has a pilot-style case which Sinn is acclaimed for. For the individuals who don’t have the foggiest idea, Sinn’s set of experiences is profoundly established in aeronautics in 1961 when Sinn started to produce route clock and pilot chronographs (the late Helmut Sinn was an educator for daze battle and previous World War II pilot).

It’s a smooth-looking watch that underlines on its utilitarian properties, yet by one way or another, it’s extremely perky in its looks.

A Video Review Of Sinn 556

Another extraordinary thing from this watch is the reflexive dark black dial. it’s too great has this nearly porcelain-like quality to it yet holds the profound dark subtleties.

All that joined with the sensibly measured 38.5 mm case does what needs to be done, making this watch quite possibly the most adaptable watch presently accessible on the watch market.


Sinn is notable for its demanding case execution. As one of the solitary brands to have their own case-making offices, under the name SUG in Glashütte, they have striking abilities. Sharp lines and wonderful completing are the least you can expect and are available on the 556i.

The 556i is one of the more completely estimated watches, and it keeps an eye out there in awe. Coming in at 38.5 x 45.7 x 11mm with 20mm carries, it’s minimal and proportional.

Toss in the 200m water resistence, and you have a watchful and adaptable design that is often loved and respected by watch lovers all over


The 556i and 556a vary just in their dials. The 556i highlights a non-mathematical dial with a sparkling surface, while the 556a has a pilot plan (huge 12, 3, 6, and 9) on a matte surface.

Both are attractive, yet there is something especially charming about the 556i’s restricted jargon of structures. It without a moment’s delay addresses military watches and something more specialized and configuration center. In that capacity, it’s extremely flexible and interesting to a wide scope of tastes

Straps And Wearability

For those of us purchasing stateside, the tie choices for the 556i are either on a calfskin for $1,090 or on an armband for $1,330.

The 20mm dark cowhide strap the 556i comes mounted on is wonderfully made.

It’s delicate, flexible, and extravagant inclination. I realize Sinn utilizes Di-Modell as a provider for a portion of their ties, so this might just structure them as well.

Sinn 104

Sinn Uhren: Modell 104 St Sa I

One of the primary things you’ll see about the 104 is the plain dark dial with counterbalance rectangular hour markers for ideal clarity.

A moment and seconds track goes around the dial border with markings down to the quarter-second imprint.

Superluminova covering is applied to the hour markers just as the vital blemish on the turning hour-long commencement bezel.

The needle-style hour and moment hands have a cool vintage look and are likewise radiant.

Gaps for the afternoon and date sit at 3 o’clock, with the two fields delivered in an insignificant sans-serif text style. Eminently, the day can be changed from English to German, and the other way around, through the crown. This is a beautiful cool and one-of-a-kind component that adds some appeal to the 104 St Sa.

A Video Review Of Sinn 104

With a cost under $1,500, we’re not astounded to see the 104 use a stock Sellita development with basic “Sinn” marking on the rotor. It actually presents great worth because of its strong development and simple functionality. While there isn’t a force save pointer, the development is outfitted with a 38-hour power save which will suit the necessities of most wearers.


Sitting at 41mm wide, 47mm haul to-carry, and 11.5mm thick, the 104’s tempered steel case is comfortable on almost any wrist.

The change made to this exceptional version is the hand-completed dot impacted case that gives the watch a truly intriguing matte look.

Sinn didn’t go too hefty on the globule impacting, as the steel actually has a touch of try to please.

It’s not exactly as quiet as one of their regimented cases. It’s about as blingy as you can get with a matte completion, and the 104 pulls off the look effortlessly.

Dial And Hands

Clarity is key with regards to the dial on the 104. A matte dark dial with white accents enhances the front of the watch.

There are enormous rectangular hash marks for every one of the hours, while little, better hash marks separate the minutes, and surprisingly more limited ones in the middle.

Sinn’s content logo sits at 12:00, while “Automatik” is imprinted in content simply above 6:00. Separated by the 6:00 file is the content “Made in Germany” that is even on one or the other side of the square.

The 104 highlights a day-date show at 3:00. You’ll track down a German/English white-on-dark day wheel flanking the dating show in a similar tone.

In light of a legitimate concern for making things simple to peruse, the day/date is laid out in a thin, fresh white bouncing box. While some may need an inconspicuous date show (the dark on a white date at 4:00 on my Sinn 856 rings a bell), the showcase on the 104 kindnesses clarity.


Obvious though the sapphire case back, there’s a Sellita SW220-1 top evaluation programmed development beating endlessly inside. This development beats at 28,800bph for a smooth second clear. Completely twisted, the development is useful for around 38 hours. You can hack the seconds for the exact time setting and hand-wind it to make it run. The top-grade development includes some pleasant completing like blued screws, striping, and perlage.

There’s an enormous gold-tone rotor that is engraved with the Sinn logo in dark. The top-grade development is a pleasant difference to the usually distinct pilot watch stylish that the watch radiates, and the straightforward case back is a decent token of the unpredictable brief period teller you lash to your wrist regularly.

Straps and Wearability

Given the dark/white/matte steel look of the 104, you can essentially toss this on a lash you need and it’ll look extraordinary. It’s a fresh start. Actually, I might want it on an olive nylon mil-tie or a tan cowhide two-piece.

Directly from Sinn, you can get the watch with either a chocolate earthy colored softened cowhide lash with twin-fasten subtleties, or you can get it on Sinn’s H-interface armband. The softened cowhide lash is incredible it’s thick, however not very thick, and it has an observable surface. It was promptly delicate and agreeable on the wrist.


Sinn 104 is the winner for us, not only just because of its looks but the variety of straps it offers, along with its movement. But there is not much difference when it comes to the quality of both of these watches and besides, Sinn 104 is a bit more expensive then Sinn 556, and then there is also the point of your own personal taste. If Sinn 556 suits your taste better then go for it!
