Redux COURG: Zero-Hour

I need to carefully apply the rules here. Let me identify the critical issues: **MOVEMENT CONTRADICTION (Rule: GROUND-TRUTH SPECS):** - Ground truth: Seiko NH35 - Source 3 states: "Seiko NH53A movement" - This contradicts the ground truth. Per instructions, I must DROP any clause stating a movement that contradicts the ground-truth specs. **VARIANT/SIBLING DISCIPLINE (VARIANT DISCIPLINE rule):** - Source 1 mentions "COURG: Zero-Hour" with "matte blue-gray titanium bezel" - Source 3 mentions "COURG" with bezel play issues - Source 5 mentions "Grade 5 Ti COURG" with "B" dial and date - These appear to be different configurations/variants of a "COURG" line within Redux - The ground truth gives me 39mm, NH35, 200m WR, but does NOT specify dial type, date window, or specific bezel finish - Since I cannot confirm which variant

Tuseno Shellback

The build quality is cited as a significant strength. Availability is a weakness, with stock running low.
