## Description
OTSUKA LOTEC No. 6 New Specifications (October Winners) is up for auction.
It is a brand new, unused, domestic genuine product.
All accessories are included except for the invoice that contains personal information (box, date-stamped warranty, instruction manual, etc.).
* The product has been inspected while wearing gloves, so there are no fingerprints.
* The second photo is for reference only.

◆ Main Changes from the Previous Model
The new specifications come with the following three significant upgrades.

[ Ultimate Durability ]
• The case material has been changed from SUS303 to the highly durable SUS316L.
• The crystal has been upgraded from mineral glass to high-hardness sapphire crystal glass.

[ Operational Stability ]
• The internal mechanism has been redesigned and improved to enhance long-term reliability and stability.

[ Premium Finish ]
• The hands and the head of screws have been given exquisite chamfering to enhance gloss and sharpness, significantly improving the overall quality of the watch.

◆ Inherited Aesthetics
It maintains a thin, unique design due to its original structure that houses the hour and minute hand unit at the 6 o'clock position. This piece is a perfect blend of practicality for long-term use and the craftsmanship that shines through beauty. Please consider this carefully.

Shipping of the item will be done via Yamato Transport or Japan Post in a cardboard box.
* The shipping box will be wrapped in bubble wrap and placed inside another cardboard box for added protection. 
As this is a high-value item, potential bidders with low feedback ratings or new accounts are kindly asked to refrain from bidding to prevent any issues. 
Additionally, please refrain from cancellation after you win the auction. No claims, no returns please.
* A video of the unboxing and capture of the serial number will be recorded to prevent replacement.

## Collector note
OTSUKA LOTEC represents a niche corner of Japanese independent watchmaking, where design innovation takes priority over brand recognition. This No. 6 iteration showcases the maker's commitment to iterative refinement—upgrading from SUS303 to SUS316L stainless steel, mineral to sapphire crystal, and redesigning internal calibers for stability—hallmarks of a brand prioritizing long-term ownership over rapid model cycles. The signature 6 o'clock subdial hand position is an unconventional design choice that signals intentional engineering rather than trend-following, appealing to collectors who value functional eccentricity and domestic Japanese manufacturing rigor.
