What watches use the LG0801B?
Invicta’s official listing for the Bolt Phantom automatic model 50784 identifies its movement as caliber LG0801B and specifies 21 jewels. This is one documented watch listing, not evidence that every Invicta Bolt model uses the caliber. Caliber Corner attributes the movement to Shandong Liaocheng Zhong Tai Watch Co., Ltd. and indexes LG0801 as a related caliber name. PTS Resources publishes the specifications, but the available sources do not clarify its corporate or supply-chain relationship to the manufacturer.

#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Before replacing a movement, verify all of the following against the watch and the seller’s documentation:
- The caliber is specifically LG0801B; a related name or similar-looking movement is not proof of interchangeability.
- The movement’s diameter and height suit the case.
- The hand sizes and two-hand layout match the hands and dial.
- The stem, case fit, and mounting points match the watch’s requirements.
- The seller accepts returns if the part does not fit or is not as described.
The available specifications establish some dimensions and hand sizes, but not universal compatibility with cases, dials, stems, hands, or other calibers. Do not select an alternative movement based on diameter alone; a matching technical drawing or reliable manufacturer documentation is needed to establish interchangeability.

What is not established
The available sources do not give a confirmed power reserve, accuracy tolerance, service interval, shock protection, or further details about winding behavior. They also do not establish that the LG0801B is interchangeable with another caliber. A watchmaker or seller may be able to confirm case-specific fit, but the listed specifications alone cannot settle it.
