Oris TT1

The TT1 sports watch collection was originally inspired by the Williams F1 team, though Oris soon started using its distinct rounded case in their diving watches as well. This design has remained largely unchanged, even with the introduction of the Aquis models. This is why many Oris fans still add the name "TT1" to the Oris Divers to this day.

The motorsport models of the TT1 have changed drastically over the years. Their lack of lugs means the bands, which come in stainless steel or rubber, appear to grow directly out of the case. The dial also has a modern design and resembles the indicators on the dashboard of a racecar. The ceramic or stainless steel bezel and flat sapphire glass help emphasize this impression.

You can find a wide selection of models in both the motorsport and diving collections. This ranges from three-hand watches to chronographs all the way up to regulators and skeleton watches.

You will find the largest selection of designs with the TT1 Day Date. Oris outfitted the 43-mm three-hand model with a day-date display at 3 o'clock. The dial comes in black, white, or dark gray with a corresponding ceramic or stainless steel bezel. The white version is particularly striking: Not only are the dial and bezel white, but so is the luminous material on the hands, numerals, and indices. Despite this, the watch is easy to read thanks to its superimposed numerals and indices that stand out against the white background. The version with a black PVD-coated case is particularly nice to look at. Its dial looks like the spokes of a wheel, and it has a bright red rubber ring between its bezel and case.

Should you choose a TT1 Day Date with a gray dial and stainless steel bezel, you will need to spend around 800 euros. Expect to pay about 1,100 euros for a white TT1 Day Date including a white rubber strap. If you feel drawn toward the black model, plan to spend between 1,050 and 1,150 euros.

The TT1 Skeleton Engine Date comes in the same case as the TT1 Day Date. However, its dial is see-through in the middle, giving the wearer a great view of the Oris caliber 733 based on the SW 200-1. The date display sits between 4 and 5 o'clock on this model. Prices for one of these timepieces start around 1,200 euros.

The TT1 Chronograph's 45-mm stainless steel case contains the ETA 7750-based Oris caliber 674. It has a small seconds dial at 9 o'clock, a 30-minute counter at 12, and a 12-hour counter and date display at 6. The bezel, which comes in either black ceramic or polished stainless steel, features a tachymeter scale and matches the color of the corresponding gray or black dial. What's more, this watch is also available with a black PVD coating and a red rubber ring between its bezel and case. Depending on which model you choose, a TT1 chronograph goes for between 1,490 and 2,100 euros.

The TT1 Worldtimer looks very similar to the original TT1 and has the same rounded case as its ancestor. As its name suggests, this watch displays a second time zone . It can be found on a subdial at 3 o'clock, which has hour and minute hands as well as a day/night display. Oris added a small seconds dial at 9 o'clock and a date display that is synchronized to the main hands at 6. The two pushers at 4 and 8 o'clock make it easy to change the timezone for the main hands: just press the corresponding pusher to set the time forward or backward by an hour. Alternatively, you can use the bezel made of vulcanized rubber. Prices for a TT1 Worldtimer sit between 1,600 and 1,700 euros depending on the model.

While the original TT1 still had a rubber bezel, the diving version received a unidirectional bezel with a minute scale. The dial design includes bullet-shaped indices covered in luminous material. As professional diving watches, TT1 Divers have a higher water resistance, ranging between 300 m (30 bar) and 1,000 m (100 bar) depending on the model. The latter are usually also outfitted with a helium escape valve.

You can find the three-hand stainless steel TT1 Divers with a water resistance of 300 m and a date display at 6 o'clock for as little as 800 euros. With a 1,000-m water resistance, a crown at 4 o'clock, and a helium escape valve at 2, its titanium sister model costs almost 1,000 euros more. Expect prices around 1,400 and 1,700 euros, respectively, for more unusual models like the Titan Regulator or the Titan Chronograph.
