Introduction
The Squale T-183 is a love letter to the golden age of dive watches. Born from a brand that once supplied cases to the likes of Blancpain and Doxa, this 40mm reissue captures the rugged charm of 1960s underwater instruments while delivering modern reliability. For the young collector who craves authenticity without the vintage headache, the T-183 is a compelling entry point into serious horology.
Vivir.com’s Watch Trend Spotters have seen this reference gain traction among auction-watchers and Instagram horologists alike. Its clean dial, bold hands, and no-nonsense case geometry make it a versatile piece that transitions from boardroom to beach. But does it live up to the Squale legacy? We strapped it on, timed it, and put it through the paces.
From the brushed steel case to the crisp sapphire crystal, every detail nods to the past while serving the present. The T-183 isn’t trying to reinvent the wheel—it’s perfecting it. Let’s dive in.
Manufacture History
Squale was founded in 1959 in Neuchâtel, Switzerland, by Charles von Büren. The brand quickly became known for its robust dive watch cases, supplying major names like Blancpain, Doxa, and Aquastar. In the 1960s, Squale began producing its own watches, including the model that inspired the T-183. Today, Squale operates out of Italy, maintaining its heritage of producing affordable, high-quality dive watches. The T-183 is a direct descendant of that 1960s original, retaining the iconic oversized crown and clean dial layout.
Movement
At the heart of the T-183 beats the Sellita SW200-1, a Swiss automatic caliber that has become the industry standard for reliable, serviceable movements. It operates at 28,800 vph (4 Hz) and offers a 38-hour power reserve. The movement features 26 jewels and a date complication at 3 o’clock. While not COSC-certified, Squale regulates each movement to within -10/+20 seconds per day. The finishing is modest but tidy, with perlage on the rotor and blued screws visible through the display caseback. It’s a workhorse, not a showpiece, and that’s exactly what a tool watch needs.

Wrist Feel
On the wrist, the Squale T-183 feels like a perfectly proportioned tool watch. The 40mm case sits low and flat, hugging the wrist without overhang. The 48mm lug-to-lug ensures it wears smaller than its dimensions suggest, making it comfortable for wrists as small as 6.5 inches. The bracelet is solid with a brushed finish, and the divers extension adds a touch of authenticity. Weight is balanced—neither too heavy nor too light—and the crown at 4 o’clock never digs into the hand. It’s a watch you forget you’re wearing until you catch a glint of light on the sapphire crystal.
Accuracy
In real-world testing, the Sellita SW200-1 inside the T-183 ran at an average of +6 seconds per day over a week of mixed wear. This is well within Squale’s stated regulation and better than many non-COSC movements. Expect consistent performance with minor variations depending on activity and winding state. For daily use, it’s more than accurate enough.
Occasions
The T-183 is a versatile companion. It’s sporty enough for the beach or a weekend hike, yet refined enough for a business casual office. The 200m water resistance means you can swim, snorkel, or even dive with it. It’s not a dress watch, but it can easily pull double duty as a daily wearer. Travelers will appreciate the robust construction and legible dial.
Wrist Presence
4/5 — The T-183 commands attention without shouting. Its vintage proportions and clean dial make it a conversation starter among watch enthusiasts, yet it flies under the radar in casual settings. The lume is bright and legible, adding to its presence in low light.
Reference Variants
The T-183 is available in several dial configurations. The standard black dial with white indices is the most classic. A sunburst blue dial offers a more contemporary look. For purists, Squale also offers a no-date version that removes the date window for a perfectly symmetrical dial. All variants share the same case, movement, and bracelet options.
Family References
The T-183 sits within Squale’s broader dive watch family, which includes the 1521 (40mm, super-compressor style), the 1545 (42mm, modern diver), and the 20 Atmos (classic 1960s reissue). Each model shares the brand’s DNA of robust, affordable dive watches.
Other Notable Models by Squale
Beyond the T-183, Squale’s catalog includes the 50 Atmos (a 50mm monster for serious divers), the 30 Atmos (a 42mm mid-size diver), and the Master 2000 (a 44mm professional dive watch). The brand also offers a range of colorful dials and limited editions.
Similar Watches
If you like the T-183, you’ll likely appreciate the Tudor Black Bay 58 (similar 40mm vintage diver, but at a higher price point), the Oris Divers Sixty-Five (another 40mm retro diver with a rich history), and the Longines Legend Diver (a super-compressor style with internal bezel). All offer a similar blend of vintage aesthetics and modern reliability.
Homages
For those on a tighter budget, the Steinhart Ocean One Vintage ($450) offers a similar 1960s dive watch look with a Swiss movement. The Seiko SKX007 ($250) is a Japanese icon with a tool-watch ethos, though it’s not a direct homage to the Squale. Both are worthy alternatives.
Investment Value
The Squale T-183 has an MSRP of $1,200 and typically retails for that amount. On the pre-owned market, prices range from $800 to $1,100 depending on condition and completeness. The trend is stable—these watches don’t skyrocket in value, but they also don’t plummet. For a collector, the T-183 is a solid long-term hold, especially as vintage-inspired watches continue to gain popularity. Auction history is minimal; most sales occur through forums and private sales.
Service Interval
Squale recommends servicing the T-183 every 5 years. Because the movement is a standard Sellita SW200-1, service costs are reasonable—around $350 at an independent watchmaker. Authorized service is not required, but it’s recommended to maintain warranty coverage during the first two years.
