Yantai Kexin Watch Co., Ltd. produces tower clocks with precise timing and no errors, primarily secured by the following technologies:

1. GPS real-time time synchronization, achieving synchronization with satellite standard time, the master control system's master clock has no cumulative error, every second and minute is precise.

2. Reliable IoT technology and feedback supervision system for the sub-clocks (large face clocks), ensuring synchronization between the large face clocks and the master clock. The sub-clocks automatically synchronize with the master clock every 15 seconds. In case of a sub-clock failure, an automatic alert is triggered along with a suggested solution.

3. Our self-manufactured movement is the core component of the tower clock, crafted from babbitt bronze for the shaft bushes and 45# steel that has undergone rigorous mechanical heat treatment, significantly enhancing the movement's wear resistance. The fully enclosed design ensures no maintenance or care is required, guaranteeing a lifespan of 50 years.

4. Professional installation staff is the guarantee for the normal operation of the equipment. Our company boasts 8 senior installation technicians and numerous well-trained高空作业 personnel. Our experience is that three parts rely on the equipment, and seven parts on the installation. Our offices and service outlets spread across the country truly ensure customers' peace of mind in purchasing and worry-free usage.

5. With years of technical accumulation, our company is capable of repairing tower clocks from all brands across the country. To assure our customers of their choice, we promise a 5-year free warranty on all repairs.

Tower Clock Grand Clock Production and Installation Process

Estimated Project Duration: Calendar Days

Including: Manufacturing Lead Time: 20 days

Transportation and installation timeline: 10 days

Production, guaranteed manufacturing timeline plan

1. Based on the signed contract. The day after the contract is signed, the company issues production schedules to all production departments (including each production workshop, technical department, and logistics center). The schedules detail the dimensions, colors, functions, and shipment times of each clock. A detailed "Material Requirement Sheet" is also attached.

2. The technical department is responsible for determining the technical solution based on the specific requirements of Party A's tender documents, and providing it to the production workshop for production. The logistics center, based on the "Material Requirement Sheet" and current inventory, drafts a detailed "Procurement Plan Sheet." The procurement plan is then issued to: electronic component procurement staff, outsourcing procurement staff, and bulk material procurement staff. The required approximate funds are also notified to the finance department.

3. Begin procuring various materials starting from the second day, with priority given to the urgent supplies needed for production.

4. The company's existing stock of materials and spare parts, such as control systems and cores, will be immediately put into production according to contract requirements. By the 3rd to 13th day, the basic manufacturing of control systems and cores will be completed. They will then progressively enter the debugging and trial operation processes.

5. The clock face manufacturing is essentially completed between the 3rd and 13th day (the exterior components do not require adjustment).

6. All packaging materials will be in place and wooden boxes for packaging completed by the 8th to 11th day.

7. All debugging must be completed within the 18th day, followed by inspection prior to packaging, and completion of various documentation and forms required for packaging.

8. All packaging is completed by the 19th day.

9. Notify Party A that the shipment is ready for dispatch, and confirm with Party A the specific unloading location and installation time.

10. Installers arrive at the installation site ahead of the agreed time by both parties to prepare for the installation. The following day, they inspect the goods with Party A and begin the installation process.

Section II: Clock Equipment Transportation and Installation Plan:

(Part One) Packaging, Shipment, and Transportation Plan

1. In terms of packaging, for general control instruments and computer accessories, we use cardboard boxes, which are lined with shock-absorbing foam and moisture-proof plastic bags. For clock faces, valuable items (such as control boxes, clock hands, dials, etc.), and goods weighing over 20 kg, we add an additional wooden crate (made of high-quality plywood) outside the cardboard box. Similarly, shock-absorbing foam is also installed between the wooden and cardboard boxes. All packaging is neat, aesthetically pleasing, and reliable, loaded onto trucks according to road transportation requirements to ensure the items arrive at the destination intact.

2. Each packaging box is accompanied by a detailed product packing list, factory quality certificate, quality inspection certificate, manual, etc. The box is sealed after being inspected and approved by the inspector.

3. Each packaging box is imprinted with the shipper, departure station, consignee, destination, product name, gross/net weight, total number of packages in this shipment, contract number, and the "Three Protection" symbol.

4. In terms of transportation, for this shipment of *** equipment, our company will select the most suitable mode of transportation, such as road or rail, based on the installation location of the tower clock project and the requirements for equipment transportation security. We ensure the safe, accurate, and timely delivery of goods to the destination. Any losses due to loss or damage will be borne by us. Within 48 hours prior to the shipment of the equipment, we will fax the recipient the following details: the name of the station for equipment installation, quantity, estimated installation date, contract number, material name and quantity, gross weight, volume, amount, name of the transportation vehicle, and the equipment shipment schedule.

5. Arrival Inspection and Handover

Upon arrival at the buyer's destination, our project manager and the buyer's representative will jointly inspect the goods in accordance with the contract. The inspection scope includes the quantity, specifications, quality, and performance parameters of the equipment. Both parties will sign and seal the delivery (receiving) document, which serves as a crucial basis for operational handover. In case of goods that do not meet the buyer's requirements, the buyer has the right to refuse acceptance or request a replacement, with all associated costs borne by our company.

(II) On-site Inspection and Installation Entry

1. On-site Installation Inspection

1) Upon arrival of the goods on-site, the installation personnel will inspect the number of packaging boxes and their condition for any damage or missing items, in accordance with the "Shipment Registration Form," together with the recipient.

2) Inspect the goods inside the packaging boxes with the buyer, checking off each item as listed on the packing list.

3) Briefly describe the names, quantities, uses, and storage requirements of various goods to facilitate the provider in securing a safe storage location.

2. Installation On-Site

1) All goods will arrive at the designated location according to the installation schedule as per the contract or mutually agreed upon by both parties. Prior to installation, a storage location for the goods will be arranged with Party A to ensure a safe storage for the uninstalled goods.

2) Collaborate with the buyer to establish installation conditions and make modifications to any conditions that do not meet the requirements for safe and smooth installation.

3) Inform the buyer of the approximate time for inspection to allow for preparation.

(3) Clock Equipment Installation

Equipment Installation Steps:

1. Assemble the clock face on the designated work surface.
