Description from the seller
(SHIPPING FROM SWEDEN, NO TAXES IN EUROPE)
Seiko Prospex "Sumo" Automatic Diver – SBDC083 (JDM / 6R35-00A0)
For sale is the robust and highly respected Seiko Prospex "Sumo" (3rd Generation). This specific model is the Japanese Domestic Market (JDM) release, reference SBDC083 (known internationally as the SPB101). The 3rd generation of the Sumo brought highly requested upgrades to the fan-favorite diver, most notably a scratch-resistant sapphire crystal and the impressive 6R35 movement boasting a 70-hour power reserve. With its sweeping case lines and aggressive bezel, it remains one of Seiko's most iconic modern dive watch designs.
Technical Specifications:
- Model/Reference: SBDC083 (Case Ref: 6R35-00A0).
- Movement: Caliber 6R35 Automatic (Date, manual winding, hacking, 24 jewels, 70-hour power reserve).
- Year Manufactured: April 2022 (Serial Number: 240195).
- Date of Purchase: March 28, 2023 (per Yodobashi Camera Guarantee Card).
- Case Material: Stainless steel.
- Crystal: Sapphire crystal.
- Diameter: 45.0 mm.
- Thickness: 12.9 mm.
- Lug-to-Lug: 52.6 mm.
- Water Resistance: 200m (Diver's Watch).
Special Features: JDM release, upgraded 70-hour power reserve, large luminescent indices and hands (Seiko LumiBrite) for superior underwater legibility, and the signature oversized bezel typography that gives the "Sumo" its nickname.
Condition Report:
- General Condition: The watch is in good, honest pre-owned condition. The stainless steel case and bracelet show light surface wear and minor scuffs consistent with careful, regular use. The bold case lines remain sharp.
- Dial & Crystal: The matte black dial and the upgraded sapphire crystal are in pristine, scratch-free condition.
- Bracelet: Mounted on its original stainless steel bracelet featuring a diver's extension. Based on the mandrel measurement provided in the photos, it is currently sized for an approximately 17 cm to 17.5 cm wrist.
Timekeeping & Mechanical Health: The 6R35 movement is functioning, winding smoothly, and the date changes crisply, but the provided timegrapher readings indicate it is currently running slightly outside of factory specifications:
- Face Up: Running at +37s/day with a beat error of 0.3ms and an amplitude of 217°.
- Face Down: Running at +22s/day with a beat error of 0.7ms and an amplitude of 199°.
- Angled (Natural Wrist Position): Running at +38s/day with a beat error of 0.2ms and an amplitude of 195°.
- Diagnostic Note: The factory specification for the 6R35 movement is +25 to -15 seconds per day. Since it is running a bit fast (+22s to +38s) and the power delivery (amplitude) is hovering on the lower end (around 195°–217°), a professional regulation or standard service is recommended to bring this workhorse movement back to its optimal timekeeping potential.
Inclusions:
- Original Seiko inner and outer boxes.
- Official Guarantee certificate (dated March 28, 2023).
- Original Yodobashi Camera paperwork.
- 6R35 instruction manual.
Production Details: Manufactured in April 2022, this piece is part of the upgraded 3rd generation of the Sumo lineage. The combination of the sapphire crystal and the extended 70-hour power reserve makes it a highly capable and modernized classic.
