Description
This TSAR BOMBA is a men's automatic watch with a skeletonised black dial in a tonneau shape. It suits anyone after a mechanical look with a visible movement at a modest price, and the silicone strap keeps it comfortable for everyday wear.
A Japanese automatic movement powers the watch and stores more than 48 hours of energy. The case is stainless steel and 15.5 mm deep, whilst the dial sits under a sapphire crystal with an anti-reflective coating. Water resistance is rated at 50 metres, and the lug width is 22 mm.
The skeleton dial is the main attraction, giving a direct view of the movement beneath. Luminous hands and markers help with reading the time in low light, and the silicone strap resists sweat and moisture, so it copes well with rain, hand washing and a casual swim.
Frequently Asked Questions
Can I swim with this TSAR BOMBA?
The TSAR BOMBA is rated to 50 metres (5ATM), which generally covers rain, hand washing, showers and a casual swim. It is not made for diving or fast water sports. Make sure the crown is pushed in fully before any contact with water, and avoid hot water, which can wear the seals over time.
Is it suitable for daily wear and sport?
With a stainless steel case, sapphire crystal and a sweat resistant silicone strap, this TSAR BOMBA copes well with daily wear, including light hiking or fishing trips. At 15.5 mm thick it has some presence on the wrist, so it suits casual outfits better than a slim shirt cuff.
How long does it run when not worn?
The Japanese automatic movement stores more than 48 hours of energy, so after a good spell on the wrist it should keep going through a weekend. If it has stopped, set the time and wear it for a while to bring it back to full power.
How does it compare with a standard round dress watch?
Compared with a typical round dress watch, this one has a tonneau shape and a skeleton dial showing the movement. The silicone strap and 15.5 mm depth also give it a sportier look. For something slim and formal, a leather-strapped alternative would be a better match.
Will it fit my wrist and can I change the strap?
The strap fits a 22 mm lug width, so many standard 22 mm straps will fit, including leather ones for a more formal look. The case is chunky at 15.5 mm thick and the watch weighs around 130 g with strap, so try it on a medium to larger wrist for best comfort.
Does it need a battery or regular service?
As an automatic, it needs no battery and runs on wrist movement. A watchmaker will generally check lubrication every few years and test the seals regularly so the 50 metre water resistance stays reliable. Have the gaskets checked before swimming if it has been a while.
Editor's take
Tsar Bomba aims at those who want the look of a mechanical skeleton watch without paying luxury money. The TB8208SGLZ pairs a black tonneau case with a skeleton dial, giving it a bolder profile than the usual round dress watch, even though the listing places it among dress watches.
A Japanese automatic movement sits at the heart of it, storing more than 48 hours of energy, so the watch can rest over a weekend and still be running on Monday morning. Above the dial is a sapphire crystal with an anti-reflective coating, a pleasant surprise at this price, and the case is stainless steel.
There are limits worth knowing about. Water resistance is 50 metres, enough for rain and a quick dip rather than serious water sport, and the movement maker is not named, so finding a UK service centre or BHI registered watchmaker familiar with it may take some effort. The silicone strap is practical but gives the watch something of a sporty, informal feel.
It suits anyone who enjoys watching a movement at work and wants an eye-catching automatic for everyday wear. Should a named calibre and a proven service network matter more, a Seiko 5 or Orient automatic is the sensible alternative in a similar price bracket.

High-quality materials lay the foundation for durability
No more glare when checking time in bright sunlight or office lighting—clear readability anytime, anywhere; Wash hands, splash rain, or sweat through workouts without worry—whether for business meetings or weekend hikes.

Japanese Automatic Movement
The TB-8208SGLZ is powered by a Japanese automatic movement that winds from wrist motion, so there is no battery to replace. A sapphire crystal sits over the dial and resists everyday scratches, which keeps a dress watch face clear and legible over years of wear.

Multiple colors to suit different styling needs
The TB-8208SGLZ is offered in several color options, so the watch can follow your wardrobe rather than dictate it. The stainless steel case and silicone strap stay consistent across versions, with the dial and finish choices setting the tone from formal to casual. Pick the one that suits how you dress.
