Product Description
Product Specifications
The SINN 104 Collection is a family of pilot’s watches, all designed using the highest quality materials and SINN technologies. The classic look of each of the watches makes them timeless and eternally stylish and the automatic movement ensures they will be reliable for generations to come. All of the watches in the collection have the distinctive features of a SINN 104, but each has its own unique look, whether it be the colour of the dial or the strap. These luxury watches have been designed to withstand adverse conditions whilst maintaining an elegant look on the wrist. Perfect for the style conscious adventurer, the SINN 104 has been precisely engineered to be a precise and reliable timepiece with the classic, luxury look of the pilot’s watch.
Core Features of the Sinn 104 Collection:
- The SINN 104 Collection features five distinctive designs of the classic pilot’s watch.
- All of the watches in the collection have cases and lugs made of polished stainless-steel.
- A captive pilot’s bezel (a SINN technology) is attached securely inside the case. The bezel can be rotated on both sides and has a luminous triangle as a key mark at the 12 o’clock position.
- Each watch features scratch-resistant sapphire glass to protect the dial with anti-reflective treatment on both sides. Sapphire glass is also used to create the transparent back of the watches and this is anti-reflection treated on the interior. The transparent back allows the wearer to observe and enjoy the mechanical movement inside.
- The SINN 104 watches are all waterproof and pressure-resistant to 20 bar. They are also low pressure resistant. The screw-fastened case back and crown are designed to ensure this water-resistance. All of the watches meet the technical requirements for waterproofness, as set out in standard DIN 8310.
- The watches are clearly structured for optimal readability. The functions include hours, minutes and seconds, date display, day of the week display and the pilot’s bezel. The date aperture is at the 3 o’clock position.
- Every SINN 104 watch is powered by an automatic, self-winding movement of the calibre SW 220-1. This movement uses 26 bearing jewels and 28,800 semi-oscillations per hour to power the timepiece. It also has a seconds stop function and is anti-magnetic as per DIN 8309.
Model Specifications 104.011-BL50205002401A:
- This watch features a matte black dial.
- The hour, minute and second hands and Arabic indices are coated in luminescent colour for easy readability in all lights.
- The dial features hour and minute indices.
- This watch has a case diameter of 41mm, a band lug width of 20mm and a case thickness of 11.5mm. Without a strap, the watch weighs 73 grams.
- This model is finished with a brown leather cowhide vintage-style strap. It has decorative black stitching and fastens with a pin buckle. The buckle features the Sinn logo.

I ordered the Sinn 104 with the vintage cow hide leather strap. On the Sinn website, and on here, the strap colour looked too light and rather plain. The leather strap I wanted was dark brown vintage leather, but that had a long lead time. So I decided to order a metal H link bracelet as well. This only cost me another forty pounds more than ordering the watch fitted with the metal bracelet, which I really liked anyway, so seemed a good option if I did not like the leather strap. When the watch arrived the leather strap looked much darker than the photo’s suggested and whilst plain, works really well with this watch.
The watch itself is exactly what I wanted and looks even better in person. I have a six and three quarter inch wrist and the leather strap fits really nicely, all be it I have to tighten it to the next to last hole. I have since sized and tried the metal H link strap and had to remove three links to get a perfect fit after adjusting the clasp.
The watch is easy to read and the bezel easy to set with no play. It lines up perfectly with the inner minute scale. The only small gripe I have is the time keeping - the watch gains about 10 seconds a day. So I may it regulated at some point. There is no guide on the Sinn site to indicate what the tolerance should be. will give it another few weeks and see how it is then.
Build quality is excellent and it looks stunning. It makes an excellent pilots watch and the mission timer bezel was much easier to see without resorting to my glasses, than my 22 year old Brietling B1. I suspect this watch will replace my B1 as my go to watch. The B1 is a Swiss Army knife when it comes to pilot watches, but as it and I get older, it is getting hard to read in the cockpit without glasses these days. No such problems with the 104.
So in summary, a stunning watch. The leather strap looks great and is very comfortable, it will probably be the strap of choice for everyday use. The metal bracelet makes the watch look far more expensive than it is! It turns the 104 into a really nice, functional dress watch.

Very enjoyable experience buying from First Class Watches. My thanks to Rowland for answering my questions. I ordered the watch on Monday at 14:30 and it arrived10:00 the next morning via DPD! Very good service all in all. I did not really need to use the DPD tracking service as First Class sent me regular updates.
I have been looking at Sinn watches for a wile, and in particular the Sinn 104. I wanted a simple, functional, and readable aviation watch that did not require reading glasses to see! I had not seen one in person, so the 30 day returns policy was attractive. I will not be returning the watch as it exceeded my expectations!
A very well made and attractive watch that looks even better than any of the many photograph's I examined! I really wanted the vintage dark brown leather strap but they seem to be on back order, so I gambled, and ordered the cowhide strap I also added a metal bracelet. Actually this worked out to be £10-20 more expensive than ordering the watch with just the steel bracelet, so a good deal! I was not sure about the cow hide strap as the photographs made look it too light in colour and rather plain! In the flesh it is much darker, even more so than the attached photo. The strap appears to be very good quality, and is a perfect for my seven inch wrist. The colour really suits the watch and it is going to be a while before I fit the metal strap!
Time keeping has been very good so far - the watch gains about eight seconds a day! Feels very light on the wrist. Both the watch and the metal bracelet came with good quality strap tools. The metal bracelet even came with a bottle of thread lock!
The 104 may well replace my trusty 22 year old Breitling B1 as my go-to watch for flying. The B1 is a Swiss Army knife when it comes to aviation watches but is getting hard to read as I get older. As watches go I think this watch was very good value given the build quality, functionality and design.
Many thanks to First Class watches for the excellent service. All the great reviews I read regarding the Sinn 104 and First Class watches were very accurate. I would strongly recommend both to anyone.Written by:Victor Peirce
