The blue ceramic bezel with two-tone bracelet is reference 83300 SY-BE-248; black- and green-bezel versions are also part of the three-hand collection. This is a guide to the watches and reported specifications—not a hands-on review of the blue-bezel reference.
Which Seascoper 300 Bicolor is this?
“Seascoper 300 Bicolor” refers to several three-hand combinations, not just one watch. TITONI’s official US listing identifies the blue ceramic bezel and steel/yellow-gold-PVD bracelet model as reference 83300 SY-BE-248. Monochrome’s 2024 launch coverage also lists black- and green-bezel variants, as well as a green-bezel configuration with a steel bracelet.
These are distinct from reference 94300 SY-BK-731, a separate two-tone chronograph with a bi-compax dial and Sellita SW510 BH a movement. The chronograph is not one of the three-hand Bicolor watches.
Design and specifications
The blue-bezel 83300 SY-BE-248 pairs a stainless-steel case and bracelet with yellow-gold PVD accents. Its blue ceramic bezel frames a black dial with a date display at 3 o’clock. TITONI lists sapphire crystal with anti-reflective coating on both sides, a screw-down crown and caseback, and 30 ATM water resistance—equivalent to the collection’s stated 300 m rating.

Monochrome’s October 2024 launch report gives the Bicolor case dimensions as 42 mm diameter, 12.55 mm thick and 52.17 mm lug-to-lug. It describes gold-PVD bezel and crown, luminous gold-framed indices, and ceramic bezel inserts in black, blue or green with gold markings. These more precise dimensions are Monochrome’s reported figures; TITONI’s official product page lists the 42 mm diameter but not the other two measurements.
Movement, chronometer status and power reserve
The three-hand models use the automatic Sellita SW200-1 and include a date. TITONI describes the 83300 SY-BE-248 as a “COSC-certified chronometer” on its official product page. Monochrome reports a frequency of 28,800 vibrations per hour and a 42-hour power reserve for the collection. Fratello’s 2024 review of green-bezel reference 83300 SYS-GN-248 reports 38 hours instead. The two publications therefore give different reserve figures; neither should be treated as a universally confirmed figure for every Bicolor variant.

- DIVER-INSPIRED DESIGN — Inspired by the sea, the MDV-106B is styled after classic dive watches and delivers 200-meter water resistance at an unbeatable price point. The black resin band and stainless steel case give it a classic look, while the anti-reverse rotary bezel adds authentic dive-watch character.
- STAINLESS STEEL CASE WITH SCREW-LOCK CROWN & CASEBACK — The MDV-106B features a stainless steel case and a reliable screw-lock crown for enhanced water resistance protection. Screw-down crown and screw-lock caseback work together to keep the movement sealed and secure during water activities — a construction standard found on dive watches far above this price range.
- LARGE FLUORESCENT HANDS & INDICES FOR INSTANT READABILITY — The dial features hands and hour indices with large fluorescent areas for easy reading in low-light and underwater conditions. The clean 3-hand analog layout with date display at 3 o'clock keeps the dial uncluttered and immediately legible at a glance.
- 44MM STAINLESS STEEL CASE | 22MM LUG WIDTH | MINERAL GLASS — The case measures 44mm in diameter, 12mm in height, with a 49mm lug-to-lug length and a standard 22mm lug width — making strap upgrades effortless with a vast range of aftermarket options. Mineral glass protects the dial from everyday scratches and impacts.
- 3-YEAR BATTERY & 200M WATER RESISTANCE — Powered by an SR626SW battery with an approximate 3-year life, the case measures 49.5 × 46.3 × 12.1mm and weighs 92 grams. At 200 meters of water resistance, the Duro is versatile and suitable for all situations — whether in the water, hiking, running, or at the office.
Bracelet and fit
The two-tone bracelet has a yellow-gold-PVD center link between steel links, and Monochrome describes a folding clasp with push buttons and a diver’s extension. Fratello’s review of the green-bezel, steel-bracelet 83300 SYS-GN-248 reports a toolless micro-adjustment system. Reviewer Jorg Weppelink praised the bracelet and adjustment, while noting that he would like to see the pin-and-collar link construction improved.
At 42 mm across and roughly 52 mm lug-to-lug by the cited reports, this is a substantial watch. Weppelink found the green/steel version comfortable on his own 18.5 cm wrist, but one reviewer’s fit impression cannot predict how it will wear on another wrist. If possible, try the exact bezel-and-bracelet configuration you intend to buy.

The Seascoper 300 and Seascoper 600 are separate lines. Monochrome characterizes the 300 as thinner and less information-dense on the dial and bezel; the 600 has a 600 m rating and a different movement. The available comparison does not establish a full side-by-side specification set, so check the exact references if comparing dimensions, movement, or other details.

What to verify before buying
- Reference and finish: confirm the reference number, bezel color and bracelet finish. For the blue bezel/two-tone bracelet, look for 83300 SY-BE-248.
- Fit: consider the reported 42 mm diameter and approximately 52 mm lug-to-lug measurement, then try it on if possible.
- Price and stock: confirm the current price and availability in your region; the launch figures and US listing are not interchangeable.
- Strap compatibility: the cited sources do not establish third-party strap compatibility, so verify fit with TITONI or the seller before ordering an alternative.
