Breitling Superocean Technical Background:
| Parameter | Value |
|---|---|
| Collection | Superocean |
| Case Diameter | 42 mm (A17360, etc.) |
| Water Resistance | 500 meters / 50 ATM (A17360) / 1500 meters (A17364) |
| Crown Type | Screw-down crown |
| Crown Functions | Manual winding, time/date adjustment, water seal |
| Movement | Caliber 17 (ETA 2824-2 base) automatic |
| Instruction | Details |
|---|---|
| Normal Operation | Unscrew crown counter-clockwise, pull to first position for date setting, second position for time setting |
| After Adjustment | Push crown back to original position and tighten clockwise to ensure water resistance |
| Manual Winding | With crown unscrewed, rotate clockwise for manual winding |
| Precautions | Always screw down the crown after adjustment to prevent moisture ingress – Superocean series offers 500-1500m water resistance, making crown sealing critical |
| Thread Alignment Tip | Push in and turn counter-clockwise until you hear a “click” – threads are aligned, then tighten clockwise |
1. Remove Movement Open the case back and carefully remove the Caliber 17 (ETA 2824-2) automatic movement
2. Remove Old Crown Press the movement setting lever while pulling out the old crown
3. Clean Winding Stem Clean the winding stem threads to remove old oil and debris
4. Inspect Winding Stem Check winding stem threads for damage – replace if necessary
5. Install New Crown Screw the new crown onto the winding stem – ensure threads align without cross-threading
6. Test Functions Test crown pull/push functions for smooth operation and distinct position detents
7. Water Test Perform a professional water resistance test after installation to ensure 500-1500m rating
Important Note: The Superocean series has extremely high water resistance ratings – the crown is a critical component of the water seal system. Improper installation may allow moisture to enter and damage the movement. Professional installation by a watchmaker is strongly recommended.
Inspection Period Check crown locking feel and gasket condition every 2-3 years
Stripped Thread Treatment If crown feels rough or fails to lock, threads may be worn – replace the crown (and case tube)
Cleaning Wipe crown surface with a soft cloth; avoid chemical solvents
Gasket Replacement Replace the crown gasket when replacing the crown
Replacement Criteria Replace if crown shows stripped threads, fails to lock, plating wear, or thread damage
Water Damage Treatment If water enters due to an unscrewed crown, immediate service is required – check movement for damage
Q1: What is the original water resistance of these Superocean models?
A: The A17360 and A17340 have a water resistance rating of 500 meters (50 ATM / 1650 feet) . The A17364 has a higher rating of 1500 meters (150 ATM) . The crown is a critical component for maintaining these high water resistance levels.
Q2: What movement powers these Superocean models?
A: The A17360, A17340, and A17364 are powered by the Breitling Caliber 17, which is based on the ETA 2824-2 automatic movement. This movement features a 38-hour power reserve, 25 jewels, and a frequency of 28,800 vph (4 Hz).
Q3: Why does my crown feel rough when screwing down?
A: Roughness when tightening often indicates dirty or damaged threads, or a worn gasket. Stop immediately, clean the threads, and inspect for damage. If the problem persists, the crown or case tube threads may be worn and require replacement.
Q4: What should I do if my crown won‘t screw down?
A: First, clean the threads on both the crown and case tube. If it still won’t engage, the threads are likely stripped. In this case, both the crown and case tube should be replaced together as a set. After replacement, a professional water resistance test is mandatory.
