Modello Tre ref. U3-RUF-B is a Made in Italy chrono-diver. It features a matte black dial with RUF yellow logo and two concentric circles subdial with markers in Super-LumiNova® GL yellow and matte black aluminium insert with raised lume dot.
Time is indicated, thanks to the matte black ladder phantom H+M, reverse lollipop S, Super-LumiNova®GL yellow tip. The 2.5 mm thick double domed anti-reflective sapphire crystal provides the best performance in every light condition.
The black DLC brushed solid 316 stainless steel case, the screwed-in 2 mm thick caseback, the 8 mm diameter crown coupled with fat 5.5 mm screw-in pushers, together with the high quality gaskets set provide a water resistance tested individually to 30atm=300m=1000ft.
Timing accuracy is guaranteed by the VK64 meca-quartz movement tuned to 32,768 Hz for 3 years battery life, with 1/5 of a second indication plus 60 minutes counter. Comes on a black nylon NATO strap with DLC black brushed finish hardware signed UNIMATIC.
The screw-down caseback features a RUF engraving and the individual progressive number. The watch is covered by a 24 months worldwide warranty and is part of a unique edition of 100 pieces.
FAQ Frequently Asked Questions
What is the difference between the Automatic, Quartz and Meca-Quartz movements?
Automatic movements are powered by the motion of your wrist and prized for their craftsmanship. Quartz movements run on a battery for maximum precision and low maintenance. Meca-Quartz pairs a quartz base with a mechanical chronograph module, combining accuracy with a mechanical feel.
Are UNIMATIC watches truly professional diver tools?
Yes. Every diver is water resistant to 300m, individually pressure-tested, and built around a screw-down caseback and crown with a mono-directional safety bezel, fully rated for professional diving.
Why is every UNIMATIC watch individually numbered?
Each piece is produced in a strictly limited edition and numbered by hand on the caseback, guaranteeing its authenticity and its place within the series.
How durable are UNIMATIC watches for daily wear?
The 316L stainless steel case, double-domed sapphire crystal with anti-reflective coating and 360° protection system are engineered to take daily knocks in stride, from the desk to the water.
What kind of lume is used for low-light visibility?
Hands and indices are treated (unless stated) with Super-LumiNova® colours picked to match the design details, delivering a strong, long-lasting glow for clear legibility in low-light and underwater conditions. It is not radioactive and requires exposure to light (natural or artificial) to charge.
How can I find out the lug width on my UNIMATIC watch
All UNIMATIC watches have a lug width of 22mm.
What is the size of the strap?
All our straps are designed to fit our watches, which use 22 mm wide straps.
They are available in one size only.
To check whether the strap will fit your wrist, please refer to the size information in the product page.
Are UNIMATIC watches water resistant?
All UNIMATIC cases are engineered to provide exceptional water resistance. Every UNIMATIC watch is individually tested to ensure a minimum water resistance of 300m (30 ATM), while selected on case modello 1 featuring our enhanced case construction are tested to withstand 600m (60 ATM).
Before exposing your watch to water, always make sure the crown and, where applicable, the pushers are fully screwed down and securely tightened. Never operate the crown or pushers while the watch is underwater.
After use in seawater, rinse the watch thoroughly with fresh water and dry it completely.Please refer to your specific model's technical specifications to confirm its certified water resistance rating.
What is an automatic watch?
The UNIMATIC automatic watch is a self-winding mechanical timepiece powered not by a battery, but by the natural kinetic energy generated from the wearer’s arm movements.
Automatic watches are more sensitive to factors like temperature fluctuations, impacts, and how they are worn.
Consequently, they may not run as precisely as quartz watches, and any timekeeping variations depend on the specific movement type.
Based on experience, new mechanical watches may initially show slight time inaccuracies, which generally self-regulate over time.
What is a reference number?
A reference number is an alphanumeric code associated with each watch model (e.g., U1S-T-MP).
You can find the reference number in the documents provided at the time of purchase, such as the International Warranty certificate, or on the case-back of your watch.
Does the stainless steel bracelet fit my watch?
The UNIMATIC UBR-TLQ18 solid stainless steel bracelet is compatible with almost all the UNIMATIC lineup. Above is a chart to help you choose the correct end-link variation for your watch. Please note that the bracelet is available in two different finishes: Brushed and Sandblasted. While a bracelet may be mechanically compatible with your watch in terms of fit and attachment, it may not match the watch aesthetically if the finish is different.
What is a chronograph watch?
A chronograph is a timepiece that combines traditional timekeeping with a precision stopwatch function.
Its integrated mechanism enables the accurate measurement of elapsed time (60minutes).
By operating the pushers, you can start, stop, and reset the chronograph seconds hand with ease.
How to use the Modello Tre chronograph function?
UNIMATIC’s Modello Tre is a mecha-quartz chronograph, offering a 300-meter water resistance.
To use your watch’s chronograph function, unscrew the two pushers by rotating them downwards until they are all the way out; press the top pusher, in order to start the stopwatch, the second hand will start moving across the dial and the left minutes subdial will move accordingly.
Pressing the top pusher again will stop the chronograph and pressing it a third time, when the chronograph is stopped, will start it once again.
If you wish to reset your chronograph back to zero, simply press the bottom pusher, and the hands will immediately return to the starting position.
It is very important to remember to always screw down the pushers whenever you are not using the chronograph function, in order to help to maintain the proved water resistance. Please be aware that the second hand is dedicated to the chronograph function, it will not move if the chronograph function is not engaged.
